Numerical study of eddy current by Finite Element Method for cracks detection in structures

S. Harzallah, M. Chabaat, K. Chabane

In this paper, we try to use the finite element method of 2-D axisymmetry to solve problems in eddy current testing problems where the main idea is detecting crack's shape using the NDT-EC. Results are given for a simple eddy current…
