In order to aid in the interpretation of nondestructive eddy current inspection data this paper reports preliminary results obtained with a 3D Finite Element Model of a conducting plate with a semi-elliptical flaw for several inspection frequencies. The results include predicted impedance change patterns over a 2D scan of the flaw. The data are useful as training sets for automated evaluation of nondestructive inspection data. The numerical results were validated with benchmark experimental measurements.
