| Abstract: | Since the shape memory and recovery characteristics of shape memory polymers(SMPs)are realized by a certain thermalmechanical cycling process,the thermomechanical constitutive equations are critical for predicting the deformation and recovery of this class of materials at different constraint conditions.In this study,a new physical-based,temperature and time-dependent constitutive model was proposed.The crystallization theory was used for reference to describe the frozen fraction of SMPs,and the frozen reta... |
