Abstract
Shape memory polymers easily form different temporary shapes and recover their permanent shape even after undergoing large deformation. In this work, shape memory behavior of a typical semi-crystalline polymer is modeled and the constitutive equations for the original amorphous and the semi-crystalline phases are derived. The amorphous and crystalline phases were characterized by an Ogden and a neo-Hookean response, respectively. The model was used to simulate a typical uniaxial cycle of deformation. The results demonstrated very good agreement between simulation and experimental data.
