The present paper presents an inversion scheme that reconstructs crack profile from eddy current signals. The scheme is based upon the genetic algorithm and reconstructs crack profile from the signals obtained by numerical simulations with use of an accelerated FEM-BEM coupling code. The cracks are assumed to have uniform electrical conductivity in order to model natural cracks that occur in steam generator tubes of pressurized nuclear power plants. On the basis of calculated eddy current signals in the previous generations, the inversion scheme is accelerated by eliminating individuals that are obviously different from the global optimum solution. Reconstruction results are shown in the paper, which reveal that the scheme is very promising.
