Abstract

The BIEM coupled with surface impedances gives good results at a low cost for 3D high frequency eddy currents calculation with linear materials. We review the possible extensions to non-linear materials. We propose (and test in 3D) an original method. Based on 1D computations of the complex surface impedance. Results are applied to induction hardening processes. This paper presents essentially validations of the method of non-linear surface impedances
