This paper, starting from previous experiences in modeling the magneto-mechanical behavior of magnetoelastic materials, faces the problem of loss evaluation of a magnetostrictive device. Measurements and simulations in a prototype actuator are here presented and compared, showing a general good agreement. The model is consequently used for a reliable loss separation. The effects of magnetization bias, preload and supply frequency on electric and magnetic losses are deepened and discussed.
