Numerical analysis of eddy current testing by integral equation method

In eddy current analysis for the eddy current testing (ECT), it is essential to estimate the electromagnetic fields around cracks accurately because the fields contain information pertaining to the cracks. In order to obtain accurate solutions by the integral equation method, a method of eddy current analysis for ECT is proposed. In modeling the cracks, a crack element introduced. In order to check the effectiveness and adequacy of the proposed method, we solve the benchmark models of ECT and compare the numerical results with the experimental ones.
