A one-dimension coupled hysteresis model for giant magnetostrictive materials
This paper addresses die development of a one-dimension model for quantifying magnetic-elastic-thermal coupling and hysteresis inherent to giant magnetostrictive materials. Firstly, the anhysteretic law is modeled by considering the Gibbs free energy function, and thermodynamic relations are used to obtain the constitutive expressions. And then pinning is incorporated to describe hysteresis based on Jiles-Atherton model. The model considered in the paper is demonstrated valid by comparing the predicted results with experimental data.
