Abstract
Magnetostrictive materials can be used to construct high bandwidth actuators with ahigher force and a larger stroke than are provided by other materials. However, their use ishindered by their complex nonlinear and hysteretic response. This response displays asignificant dependence on mechanical loading. In this paper, a modeling technique isintroduced for reproducing hysteresis curves at different loads. The classic Preisach modelis used, although the approach can be used to include load dependence in other models.Predicted values are compared with the homogenized energy model and also withexperimental data.
