Abstract

This paper investigates the numerical results relating to magnetostrictive effects in an electrical steel sample. This is based upon the magneto-mechanical coupling. The magnetic field causes elastic deformation and mechanical stress changes the magnetization curve and the hysteresis loop. As the applied stress is increased, material permeability increases. Pre-stressed magnetic material may show the promise of increased power density in the manufacturing of electric machinery.
