Abstract

The paper presents an incremental hysteretic magneto-elastic constitutive description of pseudo-cubic ferro-magnetostrictive alloys, which may be used to predict the magneto-elastic response of these materials under quite general applied magnetic field and stress processes. These processes may include fully saturated major loop, unsaturated minor loop or more general types of magnetic field processes. Local stress and domain wall pinning non-uniformities assumed in the development of the model result in smooth and continuous hysteretic magnetization and magnetostriction curves which follow the magnetization and magnetization anhysteretics with a non-constant offset. Comparisons between model results and a set of high quality measurements show that the model is agrees well with experimental curves when the magnetization response is dominated by inhibited domain wall motion.
