摘要：

A numerical method is presented for the calculation of the time-dependent response of the interaction of a stratified plate specimen of linear conductor containing a planar flaw and an eddy-current induction coil fed by a current pulse. The flaw might be located on any sides of the layers of the plate specimen. The calculations are done with the help of Fourier-transform (FT). The time-harmonic responses of the system are calculated at properly chosen frequencies, and the obtained results are weighted by the FT of the excitation to provide the FT of the response. The results of the presented method can be used for various pulsed eddy-current testing (ECT) applications.
