Description

Eddy current nondestructive characterization of composite materials is complicated by the anisotropic nature of their electrical conductivities. Earlier calculations for anisotropic materials show that eddy current distributions can be quite different from the rather simple patterns produced in isotropic media, and this can have a profound effect on probe response [1-3]. It follows that proper interpretation of eddy current data in terms of microstructural material properties requires understanding of how microstructure affects electrical anisotropy and how this anisotropy is reflected in the response of an eddy current probe.
