Abstract
Shape-memory polymers (SMPs) are an emerging class of active polymers that can be used on a wide range of reconfigurable structures and actuation devices. In this study, an epoxy-based SMP was synthesized, and its thermomechanical behaviors were comprehensively characterized. The stress-strain behavior of the SMP was determined to be nonlinear, finite deformation in all regions. Strain-energy-based models were used to capture the complicated stress-strain behavior and shape-recovery response of the SMP. Among various strain energy functions, the stretch-based Ogden model provided the best fit to the experimental observations. Compared to the sophisticated models developed for SMPs, the strain-energy-based model was found to be reliable and much easier to use for practical SMP designs.
