Effect of the Strain Rate and Temperature on the Shape Memory Behavior of PMMA

Abstract

In the field of smart materials, significant scientific progress has been made over the past decade on shape memory polymers (SMPs), which appear to offer numerous advantages. Their ability to change shape under the influence of an external stimulus, such as thermal, presents a certain interest for biomedical applications and the deployment of structures. In this section, we will develop a thermoviscoelastic-viscoplastic model to predict the shape memory behavior of poly (methyl methacrylate) (PMMA) and understand its thermomechanical behavior over a wide range of strain rate and temperatures.
