摘要：

In order to describe the thermomechanical properties in shape memory polymer of polyurethane series, a thermomechanical constitutive model was developed. Ln order to describe the variation in mechanical properties due to the glass transition, coefficients in the model were expressed by a single exponential function of temperature. The proposed theory expressed well the thermomechanical properties of the material, such as shape fixity and shape recovery.
