Analysis methodologies and experimental benchmarks for eddy current testing

In this paper, we present numerical models and experimental benchmarks for eddy current testing (ECT) applications, developed within the methods and applications of nondestructive electromagnetic diagnostic (MADEND) research project. We compare and validate two different numerical methods for eddy current calculation in the framework of ECT (an integral formulation implemented on a parallel computer system and a discrete formulation based on a geometric approach) by using specifically designed experimental benchmarks and a commercial finite element method based on a differential formulation.
