A Preisach based magnetization model is presented to work specifically on highly magnetostrictive materials. The model accounts for the additional anisotropy introduced when a prestress is used to activate the high strain, by using a bimodal structure. The necessity of strain feedback to deal with the magneto-mechanical effect is discussed for Terfenol-D specifically. The model is based on a fast implementation of the DOK magnetization model, so it is suitable for real time control applications
