Eddy current modeling in composite materials: CFRPs and multifilamentary HTS tapes

International audience; In this work, we present a numerical model for a rapid computation of eddy currents in composite materials, adapted for both carbon fiber reinforced polymers (CFRPs) for NDT applications and multifilamentary high temperature superconductive (HTS) tapes for coupling loss evaluation. The proposed model is based on an integro-differential formulation in terms of the electric vector potential in the frequency domain. It allows taking into account both the high anisotropy and the nonlinearity of the considered materials.
