Analysis of isotropic materials with vector hysteresis

Abstract

This paper presents the implementation of an isotropic vector hysteresis model within a two dimensional time periodic finite element procedure, formulated in terms of magnetic vector potential. The standard vector Preisach Model is employed and an identification procedure based on the scalar Preisach distribution function is used. Nonlinearity is handled by means of the fixed point technique following the H-convergence scheme. The convergence of the procedure is assessed and the results obtained are discussed.
