Description

In this paper we report on the development of an eddy-current measurement model, which is a generalization of the one reported earlier [1-2]. Our objective is to establish a computer model that is capable of simulating eddy current NDE in generic inspection geometries. To achieve this goal, we started with an earlier version of the model applicable to a flat-plate geometry and a tightly closed crack [3]. The model has been generalized so that the current version can handle more general specimen geometries, including curved surfaces and corners. Other features of the original model were kept unchanged; for instance, it uses the boundary integral equation method, can handle tight cracks, and works for an air-core coil driven at arbitrary frequencies.
