THREE-DIMENSIONAL CONSTITUTIVE MODEL OF SHAPE MEMORY POLYMER COMPOSITES CONSIDERING RATE-DEPENDENT BEHAVIOUR

摘要

Carbon nanotube-reinforced shape memory polymer composites (CNT-SMPCs) have been widely studied in many fields because of their high mechanical properties and thermal conductivity. Theoretical models have been developed to understand the thermo-mechanical behaviour of shape memory polymer (SMP). Most constitutive models developed for SMPs are based on phenomenological models that can describe the thermo-mechanical deformation behaviour of SMPs using a continuum element. In this study, we developed a new three-dimensional constitutive model for simulating the shape memory behaivor of SMPs and CNT-SMPCs considering temperature rate dependency.
