摘要：
Motivated by eddy current inspection for steam generators of nuclear plants, inverse problems of crack shape reconstruction are discussed. Material flaws can be detected using a probe impedance trajectory which is described by hybrid FEM-BEM scheme. A parameter estimation method is presented for reconstructing the shape of the crack depth. Results of experiments with laboratory data are summarized for supporting the effectiveness and validity of the proposed algorithm.
