A Jiles-Atherton and fixed-point combined technique for time periodic magnetic field problems with hysteresis

The paper presents a finite element solution of periodic steady state magnetic field problems in soft materials with scalar hysteresis. The Jiles-Atherton model is employed for the generation of symmetric B-H loops and it is coupled with the Fixed Point technique for handling magnetic nonlinearities. The proposed procedure is applied to a hysteretic model problem whose analytical solution is available. The results show that the Fixed Point technique can efficiently deal with non-single valued material characteristics under periodic operating conditions.
