    The reinforced concrete specimens with various lengths of debonding were prepared, and the sizing of the debonding section of the specimen by electromagnetic pulse-induced acoustic testing (EPAT) was attempted. The signal time of flight between the debonding and no debonding specimens was the constant; even the debonding length was changed. In addition, regardless of the debonding length, EPAT can measure the lengths accurately. Therefore, EPAT can not only detect the presence of debonding even if the length of the debonding changes in reinforced concrete but can also measure the lengths quantitatively.

    This study proposes a numerical model to predict pipe failure based on periodic non-destructive inspections using electromagnetic acoustic resonance (EMAR). A total of 149 artificially corroded samples that simulated flow-assisted corrosion were prepared; 27 of them were plates, and others were from pipes of various dimensions. The samples were measured using EMAR, and the thicknesses of the samples were evaluated based on the fundamental resonance frequency. The results of the evaluations were compared with the actual thicknesses measured by a caliper gauge to quantify the uncertainty in pipe wall thickness evaluation. Numerical evaluations were performed to predict pipe failure probability in the future based on the results of periodic EMAR measurements. Three scenarios of pipe thickness reduction were considered, and each scenario assumed that pipe thickness measurements by EMAR were performed every five years. The actual pipe wall thickness, which is not necessarily the same as the EMAR evaluations, is estimated as a probability density function using the Bayesian approach proposed in an earlier study by the authors. Whereas this study considers only pipe rupture, the results of numerical simulations support the validity of the model especially when the corrosion rate is not constant.

    Flow accelerated corrosion generates not only pipe-wall thinning but also roughness on an inside wall. In some flow conditions, the increase in roughness can increase the mass transfer coefficient by up to 80%. It is then very important to have an evaluation tool to monitor and quantify the roughness of a pipe. This study aims to estimate the roughness by using ultrasonic attenuation. The advantage of using ultrasonic attenuation is that it utilizes the signals measured by existing ultrasonic probes, and does not require significant changes to the equipment. To evaluate the inner rough surface, this study compares ultrasonic attenuations on random and periodic rough surfaces. We used an ultrasonic broadband probe on specimens with random and periodic rough surfaces in experiments. The results indicate a significant difference between the attenuation values estimated on random and periodic roughness. In addition, attenuation of amplitude at specific frequencies also was observed. These specific frequencies implied having the potential to estimate the pitch of periodic flaws on the rough surface.

    Due to their high surface coverage, good adhesion to metal surfaces, and their excellent corrosion resistance, epoxy thermosets are widely used as protective coatings. However, anticorrosion protection of these coatings can be improved against water uptake and can be tuned by changing the chemical nature of the curing agents. In this work, a comparative study has been performed on the water uptake of an epoxy–amine based on bisphenol A diglycidyl ether (DGEBA) cured with an aliphatic amine and the same epoxy initiated with a phosphonium ionic liquid (IL). Thus, the epoxy networks were immersed in saline water solution in a controlled temperature environment. Gravimetric and electric impedance measurements were carried out for a maximum of 3 months. Results were analyzed in order to assess the water diffusion coefficients and water saturation limits. Two models, the Brasher–Kingsbury and a novel mixing rule, were applied on permittivity values. Results highlighted that epoxy–ionic liquid systems are less sensitive to water uptake than conventional epoxy–amine networks. Due to their higher hydrophobic properties the water diffusion coefficient of epoxy–ionic liquid systems are two times less compared to epoxy–amine samples and the water saturation limit is more than four times less. The analysis also shows that the novel mixing rule model proposed here is prone to better estimate the water uptake with accuracy from electrical impedance measurements.

    The Dynamic Magnetostriction (DM) measurement method as a nondestructive testing method of ferromagnetic materials, measures the DM curve using electromagnetic acoustic transducer (EMAT) to characterize material and predict the mechanical properties. Lorentz forces and magnetostriction forces contribute mainly to the ultrasonic generation. Only the range of low field, in which the magnetostriction force mechanism is predominant can be used to measure the DM curve, but the boundaries of this range are uncertain. The improved DM measurement method based on shear wave Magnetostriction EMAT (M-EMAT) is proposed and the theory of generation of shear waves is derived. For the M-EMAT, only magnetostriction force mechanism contributed to the generation of shear waves. A theoretical model for the optimization of the transducer is developed, the model is in good agreement with the experimental results. The microstructure changes caused by residual strain will affect the magnetostriction coefficient and the DM curve. Therefore, the DM curves of low carbon steel specimens with different levels of residual strains are measured by the optimized transducer to characterize the residual strain. The normalized results demonstrate that the slope of the DM curve obviously changes with the residual strain. This leads to the conclusion that the DM measurement method can be used to characterize the residual strain of the low carbon steels.

    In this paper, the conventional database type fast forward solver for efficient simulation of eddy current testing (ECT) signals is upgraded by using an advanced multi-media finite element (MME) at the crack edge for treating inversion of complex shaped crack. Because the analysis domain is limited at the crack region, the fast forward solver can significantly improve the numerical accuracy and efficiency once the coefficient matrices of the MME can be properly calculated. Instead of the Gauss point classification, a new scheme to calculate the coefficient matrix of the MME is proposed and implemented to upgrade the ECT fast forward solver. To verify its efficiency and the feasibility for reconstruction of complex shaped crack, several cracks were reconstructed through inverse analysis using the new MME scheme. The numerical results proved that the upgraded fast forward solver can give better accuracy for simulating ECT signals, and consequently gives better crack profile reconstruction.

    The influence of strong magnetic field on stress intensity factor of an interface crack is studied in this paper. The nonlinear piezomagnetic property and magnetostriction effect have been taken into consideration in the theoretical analyses. This multi-field coupled problem is solved through a sequential coupling approach. The perturbed magnetization caused by the deformation around the crack is solved under magnetic boundary conditions. After modified by the perturbed magnetization, the initial loads are updated with magnetic forces for iterative calculation. With this strategy, the distributions of the stress and displacement at the crack region approach to the real solution gradually. Numerical results show that the influence of the external magnetic field on fracture behaviors is not ignorable. For structures with interface crack serving in a strong magnetic field, e.g., the multi-layer welded structures in the Tokamak device, the magneto-elastic coupling effects have to be considered to deal with its fracture problem.

    Eddy current testing is widely used for the automatic detection of defects in conductive materials. However, this method is strongly affected by probe scanning conditions and requires signal analysis to be carried out by experienced inspectors. In this study, back-propagation neural networks were used to predict the depth and length of unknown slits by analyzing eddy current signals in the presence of noise caused by probe lift-off and tilting. The constructed neural networks were shown to predict the depth and length of defects with relative errors of 4.6% and 6.2%, respectively.

    This paper describes the detectability of eddy current testing (ECT) using directional eddy current for detection of in-plane fibre waviness in unidirectional carbon fibre reinforced plastic (CFRP) laminate. Three different types of probes, such as circular driving, symmetrical driving and uniform driving probe, were proposed, and the waviness angle was extracted from the contour map of the ECT signal by applying a Canny filter and a Hough transform. By comparing both the waviness angle estimated by ECT and that obtained by an X-ray CT image, the standard deviation (precision) and root mean square error (accuracy) were evaluated to discuss the detectability of these probes. The directional uniform driving probe shows the best detectability and can detect fibre waviness with a waviness angle of more than 2° in unidirectional CFRP. The probe shows a root mean square error of 1.90° and a standard deviation of 4.49° between the actual waviness angle and the angle estimated by ECT. This article is part of the theme issue ‘Advanced electromagnetic non-destructive evaluation and smart monitoring’.

    The aim of this research is to evaluate high temperature damage of combustion chamber made of Cu-Cr-Zr alloy using eddy current testing (ECT) techniques based on AMR sensor. The cracks in a simulated combustion chamber can be detected by multi-frequency ECT technique. Also the relative conductivity of damaged copper alloy specimens both at room temperature during tensile testing and at high temperature of fatigue and creep testing were related to the applied damage with micro cracks.

    Tensile properties of thin wall ductile cast iron containing chill structure were evaluated, and eddy current measurements were carried out to detect the chill structure which affect the tensile properties. Ten cast iron samples with six specimens were prepared. Tensile tests were performed on the four specimen of each sample and the eddy current measurement and the microstructure observation were carried out for one specimen. Tensile test results showed that chill structure shortens the elongation at break when the size or amount of the chill is large enough. Although the values of the elongation are different among samples that were cast in same mold, there is no difference on stress-strain diagram until braking. Eddy current signal indicates the difference of matrix and tensile strength. Chill structure can be distinguished with the signal distribution when the chill structure clusters, but it is difficult to find the small chill spread homogeneously. Sensitivity or resolution should be improved to evaluate various thin wall ductile cast iron samples.

    Several factors affecting eddy current hardness of spheroidal graphite cast iron were examined. Sensitivity of the eddy current hardness measurement was influenced by the coil turn number and measured frequency. In case of a 22mm diameter 400-turn coil, the applied frequency of 6kHz showed highest correlation with hardness, and 30kHz showed lowest correlation. Applying this result, we fabricated a prototype eddy current hardness tester, by which we evaluated the effects of heat treatment and surface machining methods, milling and grinding. At first, the eddy current hardness tester was calibrated on a grinding surface of ten specimens with different hardness. Each side of the same cast iron block specimens was machined by either milling or grinding. On a grinding surface, measured eddy current hardness well agreed with Brinell hardness. On the other hand, measurement on a milled surface clearly showed higher eddy current hardness than on a grinding surface. Vacuum heat treatment at 973K for one hour followed by furnace cooling clearly reduced eddy current hardness. Heating temperatures ranging from 673 to 873K for one hour had little effect on eddy current hardness, but additional heating at 733 to 833K for one hour clearly reduced eddy current hardness. Finally, the effect of heat treatment on cold rolled low carbon steel was examined. Heat treatment of the steel at 673 to 973K for one hour reduced eddy current hardness, which showed good correlation with Vickers hardness.

    This paper discusses the feasibility of characterization of graphite morphology and size in flake graphite cast irons based on electromagnetic nondestructive methods. Several flake graphite cast iron specimens whose graphite form and size are different variously were prepared, and their electromagnetic properties such as conductivity and relative permeability were evaluated systematically. The results showed that both conductivity and relative permeability depend mainly on the form and size of graphite. Especially, the conductivity has a good correlation with form and size of graphite independently from the pearlite ratio of matrix. The conductivity was found to be correlated highly with ultrasonic velocity, and the ultrasonic velocity was found to be highly correlated with amount and size of graphite. Therefore, measurement of conductivity and permeability can be considered to be well applicable to evaluate form and size of graphite in flake graphite cast irons. Focusing on the fact, DC potential drop method was applied to evaluation of graphite form and its capability was evaluated.

    The authors have discussed the feasibility of evaluation of Type IV damages of high Cr steel welds by electromagnetic nondestructive evaluation methods. As the first step, effects of isothermal-aging on magnetic properties were systematically examined. Ac magnetic properties at relatively high frequencies changes in accordance with Larson-Miller parameters of the isothermal-aging specimens of modified 9Cr-1Mo steel. Especially, ac losses at 100kHz correlate well with hardness of the specimens. Base on the findings, eddy current method was applied to the same samples. Signals linking the ac losses correlate well with hardness.

      Eddy Current Testing (ECT) was applied to non-destructive evaluation of artificial cracks, 0.25 mm in width made by electro discharge method, and internal defect, 1.6 mm diameter drill hole under the surface, in cast iron. It is important to select suitable frequency and coil for measurement to receive higher SIN signal, because small skin depth caused by ferromagnetism of a matrix limits measurable depth and inhomogeneous structure produces strong noise signal. Measurable crack depth was less than 3 mm when using two coil method. Direction of the crack could be determined from Lissajous patterns of the ECT signal. The signal changed linearly when two coils set in right angle to the crack, but showed curve when two coils set parallel with the crack. On the other hand, detection of internal defect of cast iron was difficult because change in Lissajous patterns of the ECT signal by a drill hole under 0.5 mm from the ground surface was weak as compared to higher noise signal induced by inhomogeneous matrix.

      Since electric conductivity and permeability of spheroidal graphite cast irons depend on their matrices such as ferrite, pearlite and cementite : ledeburite and free cementite, there is a possibility that eddy current method can characterize matrices of spheroidal graphite cast irons. In this study, electromagnetic properties of spheroidal graphite cast irons were examined in order to discuss the possibility of detection of cementite in spheroidal graphite cast irons using eddy current method, and consistency between electromagnetic properties and eddy current signals was discussed. For the purpose, three kinds of specimen groups were prepared : (1) 8 specimens of a 5-step bar type, (2) 10 specimens cut from actual casting products and (3) 4 specimens of 2 to 6 mm thickness. Results of measurement of electromagnetic properties showed that both conductivity and permeability of cast irons decrease as cementite content increases, respectively. The eddy current method was applied to characterize specimens of different contents of ferrite, pearlite and cementite. It was found that inclusion of cementite can be detected through eddy current signals on the complex plane of impedance, in addition to ferrite and pearlite ratio. It is consistent with the results of electromagnetic measurements, and supports for the fact that the eddy current method has a capability to detect cementite nondestructively.

    A triangular loop current model visualizes exciting currents giving the desired magnetic field distribution by means of inverse problems. Combining a set of three line currents as a triangular loop represents magnetic field sources holding the conservation of currents, as well as magnetic fluxes. For designing exciting coils, at first, the region for the coils is filled with the current elements. Second, the desired magnetic field distribution represented as an input vector derives a system of equations from the relation between the magnetic field distribution and currents. Third, solving this ill-posed linear system determines the intensity of current in each of the elements. Finally, the current vector visualization performs designing exciting coils. The applications in homogeneous and concentrated magnetic field generation are presented.

    This paper discusses an imaging of eddy current testing (ECT) data for surface breaking evaluation. The multicoil ECT probe utilized in this paper consists of transmit-receive (TR) type sensors as array elements to obtain the information on crack directions and deep situation. Switching two direction scan modes gives two-dimensional vector mapping as ECT images. The ECT signals of the TR type sensor also give the information on crack directions from their variation displayed on the complex number plane. Extracting a complex number component of the signals makes it possible to visualize directions of proximate EDM notches.

    Abstract We study the stability/instability of skyrmions under mechanical stresses by Monte Carlo simulations in a 3D disk composed of tetrahedrons. Skyrmions emerge in chiral magnetic materials, such as FeGe and MnSi, under the competition of ferromagnetic interaction (FMI) and Dzyaloshinskii-Moriya interaction (DMI) and are stabilized by the external magnetic field. Recent experimental studies show that skyrmions are also stabilized/destabilized by uniaxial compressive stress perpendicular to or along the magnetic field direction. These phenomena are studied by using a 3D Finsler geometry (FG) model. In this 3D FG model, the DMI coefficient is automatically anisotropic by a geometrically implemented coupling of strains and electronic spins. We find that skyrmions are stabilized (destabilized) by extension (compression) stress along the direction of the applied magnetic field consistent with reported experimental data. This consistency implies that the 3D FG model successfully implements the magnetostrictive or magneto-elastic effect of external mechanical stresses on chiral magnetic orders, including the skyrmion configuration.

    Remote Field Eddy Current Testing (RFECT) can detect defects in a wider range of a specimen than conventional ECT, and is used for inspection of outer pipe wall thinning using inner coils. The aim of this study is to apply surface coil RFECT to pipe wall thinning and to propose the design of probe that can evaluate thinning with various size. Experiments and numerical analyses are performed on SUSS 16 austenitic stainless steel plates with slots. First, numerical analyses are verified through the comparison with experimental results. Then, the survey of probe parameters is performed, such as distance of between exciting and pick-up coils, and the test frequency. Capability of the optimized probe shows that surface coil RFECT can be used as a screening tool of inspection of pipe wall thinning.

    The aim of this study is to evaluate structure changes due to creep damage of mod. 9Cr-1Mo steels by incremental permeability method. For the purpose, magnetic incremental permeability is measured in thermal aging specimens in which precipitations change and creep specimens in which both precipitations and dislocation change. Featured parameters to quantify the magnetic incremental permeability are extracted, and discussed in relation to structure change by creep damage. As a result, peak-to-peak distance of incremental permeability curve decreases in increasing of Larson-Miller Parameter which is relative to precipitations. In addition, incremental permeability amplitude decreases in increasing XRD integral width. Both precipitation and dislocation can be evaluated based on behavior of incremental permeability.

    In this study, Electromagnetic Acoustic Resonance method (EMAR) is applied to online monitoring of pipe wall thinning, and accuracy and stability of measurement is discussed through field tests using a large-scale corrosion test loop. Although EMAR has a high capability of evaluating thickness or ultrasonic velocity, targets are usually limited to ones with simple geometry such as plates. In order to measure thickness of pipes with complicated wall thinning, superposition of nth compression for data processing method is applied to extract thickness information from spectral responses. Results of two-month monitoring show that EMAR with the proposed signal processing method has a capability of evaluating pipe wall thinning with the accuracy of several m at high temperature of 165 degrees C.

    No effective inspection method exists at present for detection and evaluation of wall thinning under the reinforcing plates of T-tubes in nuclear power plants, and the establishment of the inspection method is highly required. In this study, eddy current testing (ECT) with controlled exciting field is applied to evaluation of wall thinning under the reinforcing plates of T-tubes, and their feasibility is discussed. In order to induce eddy current field in deep region of doubled plates, pulse excitation and probe structures are investigated. Through experiments using specimens simulating tubes with reinforcing plates, it is shown that pulsed ECT and conventional TR type eddy current probe with optimized configuration have a capability of detecting and sizing the wall thinning under reinforcing plates.

    The experiments of residual strain testing with an EMAT and ECT dual probe showed that the birefringence coefficient of shear waves can generally evaluate the residual strain. In addition, since the residual strain can be tested with ECT method as a supplemental result, the dual probe is meaningful in residual strain evaluation.

    Electromagnetic acoustic resonance method (EMAR) has a high capability of evaluating thickness or ultrasonic velocity, and it is applied to the measurement of thickness, elastic constants, damping properties and so on. Since the principle of the method is based on the through-thickness resonances of bulk waves, that is, thickness oscillations, targets are usually limited to ones with simple geometry such as plates. In this study, pipe wall thinning, where the thickness changes on the curved surface, is evaluated by EMAR. For the purpose, several data processing methods are applied to extract thickness information from spectral responses. Measured spectra are obtained by an experiment using a carbon steel pipe with two-dimensional thinning machined by milling, and results of the data processing are compared in view of accuracy and stability. Finally, the data processing method is applied to the EMAR spectra of a pipe specimen cut from a mock-up test loop.

    The remote field eddy current testing (RFECT) is usually used for inspection of ferromagnetic small tubes with inner coils. The aim of this study is to clarify the precise characteristics of RFECT for inspection of flat plates with pancake coils, which has rarely appeared in the literature. The study was performed by actual experiments and computations based on electromagnetic analysis to evaluate the capability of RFECT to detect a defect and estimate the shape of a defect. This paper introduces some of the results obtained from these experiments and computations for a simple probe configuration having only one excitation and one pick-up coils. The results shows even this simple configuration enables RFECT to detect local wall thinning and roughly estimate its shape.

    Eddy current method was applied to evaluate the mechanical properties of thin wall ductile cast iron. Thin wall ductile cast iron specimens with the thickness of 4mm and 6mm were prepared. Eddy current signal and Rockwell hardness were measured at the same position of the specimen. Correlation of the signal intensity and hardness of the thin wall specimen was compared with that of thick Y-Block. Hardness of the thin wall specimen was higher than that of Y-block specimen for the same eddy current signal intensity. Change in the eddy current signal with hardness of the thin wall specimen was smaller than that of the Y-block specimen. Tensile strength of the thin wall cast iron specimen can be estimated with the correlation of hardness and tensile strength for thick cast iron. Correlation of eddy current and hardness is needed to be clarified to eavluate mechanical properties of thin wall ductile cast iron by the eddy current method.

    This paper discusses the capability of Eddy Current Monitoring (ECM) system as a in-situ evaluation method of crack propagation in a Boiling Water Reactor (BWR) environment. The ECM experiment with the eddy current probes on the outer surface of a large-scale pipe specimen, demonstrates the capability to monitor the propagation of cracks introduced from the inner surface of the specimen in a simulated BWR environment. The numerical simulation of eddy current signals shows that the experimental signals can explain the crack propagation. This provides that the ECM system is an effective method to evaluate the crack growth quantitatively.

    In this study, to apply Eddy Current Magnetic Signature Method (ECMS) to nondestructive evaluation of residual stress and strain in carbon steels, we investigated the relationship between residual stress measured by X-ray diffraction method and ECMS signals that is coil impedance trajectories during magnetization. The followings were found; a) ECMS trajectories are linear when no residual stress is applied, b) ECMS trajectories show anti-clockwise loops by compressive residual stress localized on surface by mechanical machining, c) they show clockwise loops by compressive stress exerted to ferrite phase in carbon steels after tensile test. Electromagnetic field analysis taking consideration of constitutive relation for dynamics magnetization shows that ECMS trajectories change by residual stress is ascribed to magnetic domain structure by stress.

    Diamond-like carbon in which cobalt, which is a ferromagnetic element, is dispersed in nano clusters is introduced into the adhesive bonding interface of fiber reinforced plastic (FRP). By measuring the change of eddy current signals of Co-DLC on bonding interface with eddy current testing (ECT), which is one of electromagnetic nondestructive evaluation methods, nondestructive evaluation of the failure generated in the FRP adhesive bonding interface is enabled. It was revealed that even if the ECT probe is 10 mm away from Co-DLC, the damage caused to Co-DLC can be sufficiently detected. Although the adhesive strength decreased by 18% by introducing Co-DLC, the feasibility of this method is expected as a method that enables nondestructive evaluation of adhesive bonding.

    In this study, superconducting electromagnetic acoustic transducer (EMAT) is developed to transmit strong ultrasound with controlled frequency and sound pressure of incident wave, which is expected as an effective experimental tool for mechanism study of nonlinear ultrasonic phenomena. Transmitted wave of this system was evaluated by laser Doppler vibrometer. The measured surface displacement was compared with numerical analysis of ultrasound by EMAT. The result of numerical analysis was in a good agreement with the experimental data, which indicate the developed superconducting EMAT can transmit a ultrasound with controlled sound pressure. Nonlinear ultrasounds from fatigue crack specimens were measured by the superconducting EMAT. Generations of some higher harmonics from closed cracks are confirmed for and dependence of higher harmonics on input frequency is investigated.

    This study has developed a nondestructive evaluation method of the laminate structure of carbon fiber reinforced plastic (CFRP) on the scarfed surface by utilizing eddy current, aiming for an automation of the scarf adhesive repair for huge structures such as aircraft composed of CFRP. The technique able to automatically characterize the fiber orientation and to extrude the shape of the patch of respective laminate layer on the scarfed surface, which is important in scarf repair, was developed by utilizing Eddy current testing with a mutual induction differential type probe. Since the adhesive repair is performed not depending on the advanced skill and experience of professional repairmen with this technique, it is expected that the repair of huge structures composed of composite materials could be more reasonable and easier.

    Understanding of the metal solidification is a key issue to increase the reliability of the metal processing, and the sensors for monitoring such process at high temperature is highly required. EMAT (Electromagnetic Acoustic Transducer) provides non-contact measurements, and it is suitable for measurements in high temperature. The main factor to limit working temperature of this EMAT is the Curie temperature of iron yoke. In this study we proposes to use air-cored coil as the bias magnetic source of EMAT. The pulsed-echo waveforms of an aluminum alloy specimen are measured by the present EMAT in high temperatures and shear wave velocity of the specimen at each temperature is evaluated. Back-echo signals can be identified at the range of temperature from RT to 400 degrees C.

    This study investigates the possibility of nondestructive evaluation of structural changes by creep damage of Mod. 9Cr-1Mo steel which is used for structural material of the Japanese demonstration reactor of fast breeder, JSFR. For the purpose, dislocation density and precipitations of creep specimens were quantitatively analyzed, and frequency response of dynamic magnetization process were evaluated by the magneto-optical Kerr effect measurements and the FEM analysis of electromagnetic field. Through these investigations, the relation between structural change of creep specimens and dynamic response of magnetization were organized and the mechanism was discussed. Based on the measuring principle, the creep specimens of Mod. 9Cr-1Mo steel were evaluated by the non-linear eddy current method and the feasibility of evaluating structural change by creep damage was demonstrated.

    The process to coat different electrodes on cored piezoelectric fibers, the methods to measure the mechanical, electric and piezoelectric properties of cored fibers, and the process to manufacture curved fibers were developed and the applications of cored piezoelectric fibers to bio-mimetic flow sensors and the sensors for structural health monitoring were studied. The main academic achievements are as follows. The cored piezoelectric fibers can be used in the longitudinal mode when the electrode is coated on the whole surface or the bending mode when the electrode is coated on half of the surface. In this study, a fixture was designed for the exiting sputtering machine to coat both whole-surface electrode and half-surface electrode. The dynamic model of the straight piezoelectric fibers was established and solved and formulas to estimate the piezoelectric characteristics were established based on the resonance and anti-resonance method. To meet the various applications, a process to fabricate curved piezoelectric fibers was established, and ring-shaped, arc-shaped, spiral fibers were fabricated. In the fabrication process, a fixture was used to generate the desired shape during the sintering process. Furthermore, the conditions including the atmospheric gas, sintering temperature, and used additions were optimized to fabricate high-performance fibers. As an application of the fibers, bio-mimetic flow sensors were produced from piezoelectric fibers coated with a half-surface electrode and the relationship between the output voltage of the sensor and flow velocity was investigated. The fiber was installed vertically inside a small wind tunnel with a shutter to change the flow and the output voltage signal of the sensor was measured when the shutter was closed or opened. The relationship between the maximum output voltage and the maximum acceleration of flow when the shutter is opened and closed was obtained. A fiber coated with a whole-surface electrode was used as a sensor for structural health monitoring. A GFRP plate with four embedded sensors was manufactured in an autoclave. An impact load was applied to the plate and the output voltages of the four sensors were measured and recorded. The position of the impact load was identified from the voltage signals of the sensors using a neural network. The maximum identification error of impact position is less than 5%.

    The basic properties were investigated concerning the high temperature superconducting plasma stabilizing coil. It surrounds the nuclear fusion reactor plasma in toroidal direction and catches the magnetic filed yielded by the plasma. When the Plasma Vertical Displacements (VDEs) occurs and the plasma moves from the equilibrium location, its magnetic filed changes too. Then, the superconducting currents induced in the high temperature superconducting plasma stabilizing coil and it makes the magnetic force to prevent the displacement of plasma. This coil is, however, impossible to be arranged without its division because it must be in the vacuum vessel. In this research, the dependency of division of the high temperature superconducting plasma stabilizing coil upon the plasma stability effect was investigated by the simulation code which was developed objecting the numerical analysis of the saddle-shape superconductng coils. Then, the saddle-shape model coil was manufactured with the BSCCO superconducting tapes, and the induced current in the saddle-shape coil was measured when it was exposed by the active external magnetic field. The experimental and numerical results were compared with each other, and the validity of the simulation code was verified. Next, the coupling simulation code was developed by coupling the above one with the another: the numerical analysis code for the dynamical equilibrium of plasma. The plasma stability effect by the superconducting saddle-shape coil was evaluated with this coupling code. The numerical results concerning ITER plasma showed that the enough plasma stability can be obtained even if two superconducting saddle-shape coils of 20 divisions surround the plasma.
