Abstract
The BIEM coupled with surface impedances gives good results at a low c ost for 3D high frequency eddy-currents calculation with linear materi als. In this paper, we review the possible extensions to non linear ma terials. We propose (and test in 3D) an original method, based on 1D c omputations of the complex surface impedance. Results are applied to i nduction hardening processes. This paper presents essentially validati ons of the method of non linear surface impedances; a future publicati on will be devoted to the thermal validations.
