Abstract: Shape memory polymer (SMP), as a typical smart material, has attracted great attention in the fields of aerospace, microsystems and biomedicine due to its unique shape memory properties. In order to make more accurate use of the shape memory characteristics of SMP for engineering applications, this work used phase transition constitutive and viscoelastic constitutive models for comparative simulation research. Firstly, using the classical phase transition theory of micromechanics combined with SMP materials, an explicit analytical solution of its stored strain formula was given. Through a series of experiments such as uniaxial tension, stress relaxation and thermal cycling, the parameters of the two constitutive models were obtained, and then the thermal shape memory cycle process of SMP was simulated. The numerical simulation results of different constitutive models are compared with the experimental results. The research results show that the simulation results of the constitutive model using phase transition theory are more consistent with the experimental results, and can more accurately reflect the shape memory characteristics of SMP materials.
