Prediction of a Typical Amorphous Shape Memory Polymer Behavior Considering Both Glassy and Rubbery Phases

In this study, mathematical prediction and validation of shape memory thermomechanical behavior of a typical amorphous polymer was formulated considering both rubbery and glassy phases. The constitutive model with different hyperelastic functions for rubbery and glassy phases was developed using continuum mechanics approach. A typical uniaxial cycle of deformation was considered. The theoretical results exhibited a good agreement with experimental data.
