Abstract
- A magneto-mechanical-thermal model based on a domain rotation mechanism is developed in this paper. An energy distribution parameter related to prestress and temperature is induced, which can be determined by simple experiments. Magnetization and magnetostriction of Terfenol-D at different temperatures and prestresses are calculated and estimated, which are consistent with experiments. The model can be applied to estimate prestress effects to magnetization. The results show that compressive prestress can increase to maximum using temperature of giant magnetostrictive materials.
