| Abstract: | Considering that the magnetic field-induced strain in ferromagnetic shape memory alloys arises from the field-induced motion of twin boundaries in the martensite state, a thermo-magneto-mechanical coupled model of ferromagnetic shape memory alloys is presented. With the numerical simulations of magnetic flied-induced strain, magnetic flied-induced stress, magnetization and hysteresis effect, it can prove the rationality and applicability. |
