Abstract: In this paper a new field of application of the overlapping finite element method is proposed for eddy current testing. This method, which has already been used to deal with the lift-off, is extended to the treatment of thin conducting and/or magnetic layers.

Keywords: Finite element method, dual formulations, eddy current testing, overlapping finite element
