000014125 520__ $$2eng$$aIn this work, we propose a new viscoelastic model for shape memory polymers (SMPs) based on phase transition, which has clear physical significance and includes the time history. To describe the phase transition phenomenon of SMPs, our new model has different constitutive structures above and below transformation temperature. As the proposed viscoelastic model is based on phase transition, it can be used both for different types of SMP materials and to treat large strain problems. To validate the model accuracy and show the model's capability in reproducing the shape memory effect, two test examples are predicted using the new constitutive model. The simulated and predicted results are compared with available experimental results and good agreement can be observed.
