Abstract

This paper proposes a crack sizing method in eddy current testing (ECT) for austenite stainless steel plates. The image and finite element analyses for the ECT response maps estimate size of surface breaking and crack depth, respectively. At first, template matching identifies surface breaking in fragments. Second, measuring the length of fragment gives a quasi-3D region for sizing crack depth. Third, the crack is reconstructed by iteration of fast finite element analysis. Finally, overlapping all evaluated cracks represents complicated-shape cracks. It is shown that size of stress corrosion cracking is efficiently estimated.
