The nonlinear thermomechanical relationship in shape memory polymers (SMPs) has drawn considerable attention
in many fields ranging from aeronautics to medicine largely due to their ability to withstand deformations
several orders of magnitude larger than in shape memory alloys (SMAs). At high temperatures, SMPs share
attributes with compliant elastomers and exhibit long-range reversibility. In contrast, at low temperatures they
become very rigid and are susceptible to plastic, although recoverable, deformations.
