An eddy-current model and algorithm for three-dimensional nondestructive evaluation of advanced composites

A model-based algorithm is developed for inverting eddy-current data and reconstructing flaws in advanced composite materials. The model incorporates an integral solution that is built around the Green's function computed in a companion paper. The application of certain least-squares algorithms and a numerical method of analytical continuation are described. Numerical experiments are carried out for a simulated flaw in graphite-epoxy.<>
