Description

During recent years, rapid progress has been made in modeling the interaction of nonuniform eddy-current (EC) probe fields with surface flaws and verifying these models by comparisons with experiment. Following the development of the basic analysis for nonuniform probe fields [1], the first comparison of measured eddy current signals with predictions of the theory was made in 1983 [2]. The following year brought development of a full inversion procedure for rectangular flaws [3], which was successfully demonstrated using flaw signals measured for a series of rectangular electrical-discharge machined (EDM) notches in aluminum [4].
