Implementation of a vector hysteresis model in 2D finite element analysis: Study of a RSST with anisotropic sample

Abstract

This work deals with the implementation of a vector hysteresis model in a 2D finite element code with vector potential formulation. The inverse Jiles-Atherton vector hysteresis model is used to describe the magnetic behavior law. This model allows to write naturally the differential reluctivity tensor which can be directly applied to the field calculation equations. The proposed implementation is then validated with a numerical model of a rotational single sheet tester and comparison with the measurements.
