Based on the viscoelastic theory, the shape memory behavior of SMP materials is analyzed theoretically with the aid of numerical method of finite element in this paper. The stress-strain relationship depended on temperature and time of SMP materials is described by the thermal viscoelastic integral constitutive model. A numerical simulation is carried out to compare with the experiment conducted by Tobushi (2001[6], 2005[9]), and the simulation results correspond well with the experiment, thus can provide reference to experimental studies
