  Abstract: A nonlinear hysteresis model of magneto-mechanical-thermo coupling for Terfenol-D 
  materials is presented according to Wiss ferromagnetic theory, thermodynamics relations and 
  Jiles–Atherton model. Numerical calculation and experimental results show that the mode well 
  reflects the magnetostrictive characteristics of Terfenol-D rod under the coupling of stress, 
  temperature and magnetic field. A fiber Bragg grating current
