Zusammenfassung, Abstract
In this paper, the theoretical background of nonlinear constitutive multifield behavior of the ferromagnetic phase as well as some results are presented. Both physically and phenomenologically motivated constitutive models have been developed for the numerical simulation of the nonlinear ferromagnetic/magnetostrictive behavior. On this basis, the magnetization and strain are simulated, analyzing the hysteresis behavior and other nonlinear effects. In general, numerical simulations focus on the prediction of local domain orientations and residual stress going along with the poling process to improve the efficiency of magnetoelectric coupling and reduce damage initiation.
