概要
This paper is concerned with a method for identification of crack shape in material. Natural crack is described by a layered conducting model with respect to each finite element of a sample material. Two dimensional image is obtained by eddy current testing simulator with the layered conducting model. The inverse analysis is discussed with the background knowledge of nonlinear output least square method.
