Abstract :
This paper performs a study of the effect of pulse shape on signal amplitude for TEAM Problem 27-Eddy Current NDT and Deep Flaws. A procedure is described to reduce the discretization errors in the finite element mesh. The results are compared with experimental waveforms. It is found that beyond a certain point the signal amplitude is insensitive to further decreases in the pulse turn-off time.
