Abstract
Micro-magnetic nondestructive evaluation and testing techniques are particularly efficient for the evaluation of plastic strain in steel components. A new method derived from the magnetic incremental permeability experimental setup and called Eddy Current Magnetic Signature (EC-MS) seems to be the particularly adapted for such evaluation. Numerical simulation of EC-MS has never been done before. In this article, the EC-MS method is described first, then a lump scalar phenomenological model based on a modified Jiles-Atherton model and extended to dynamic behavior is proposed for its simulation. All the simulation details are exposed and justified with physical observations.
