Description

Eddy current probes have been widely and successfully used to detect surface breaking flaws in metals. It is quite natural to ask if the eddy current signal can be used to characterize the flaw, i.e. determine its type, length or depth? This paper is a “report in progress” on just this question. The basic strategy is to find an eddy-current flaw characterization problem simple enough that an analytic solution is possible. This analytic solution is then used to uncover the elements generic to eddy-current characterization (inversion) methods.

A Laplace Transform Based Inverse Method for Flaw Characterization by Eddy Currents
