Enhancement in three-dimensional non-destructive evaluation of real cracks from two-dimensional simulated eddy current testing signals is reported ESTER-C 500MG ORANGE in the paper.A new uniform eddy current testing probe is employed for the inspection.All three spatial components of the perturbation electromagnetic field are acquired during two-dimensional scan of the probe.The ECT signals due to partially conductive cracks are simulated by a fast forward FEM-BEM solver using a database.

Two crack models are proposed for the inversion using the tabu search stochastic method.The former model has a cuboid English leathers shape and the latter one reflects a more complex geometry.Numerical results of the three-dimensional reconstruction of partially conductive cracks from simulated two-dimensional signals are presented and discussed in the paper.
