ANALYSIS OF ISOTROPIC MATERIALS WITH VECTOR HYSTERESIS

This paper presents the implementation of an isotropic vector hysteres is model within a two dimensional time periodic Finite Element procedu re, formulated in terms of magnetic vector potential. The standard Vec tor Preisach Model is employed and an identification procedure based o n the scalar Preisach distribution function is used. Nonlinearity is h andled by means of the Fixed Point technique following the H-convergen ce scheme. The convergence of the procedure is assessed and the result s obtained are discussed.
