磁気特性に基づく欠陥形状評価及び寿命予測ツールの開発

抄録

　In this paper, a summary of the software which authors are currently developing for the purpose of Non Destructive Inspection and lifetime evaluation is explained. In addition, the mathematical background of the calculation carried out inside of the software is remarked, with particular emphasis on the inverse problem based on Tikhonov's regularization method, the L-curve method and the mesh-independent stress analysis based on the extended finite element method (XFEM).
