Abstract: In this paper an approach is proposed for the taking into account of the displacement of the probe in the finite element simulation of eddy current testing. The proposed approach allows to reduce the difficulties associated to the finite element meshing. The computations are performed using two finite element formulations. Two test ECT problems are proposed. Numerical results are compared with experimental data.
