Deterministic methodology stabilizing with SVD and fuzzy inference for crack shapes on ECT by laplace transform BEM

摘要

This paper presents an inverse analysis which are formulated by the BEM with Laplace transform and the matrices for inverse analysis are stabilized with singular value decomposition (SVD) and Fuzzy inference. The proposed method is applied to a simple problem on the eddy current testing (ECT). Consequently, it is shown that the method is applicable to the crackshape estimation of ECT.
