Shape memory polymers (SMPs) are a new type of smart materials, they perform large reversible deformation with a certain external stimulus. The properties (e.g., stiffness, strength and other mechanically static or quasi-static load-bearing capacity) are primarily considered for conventional resin-based composite materials which are mainly used for structural materials. By contrast, the mechanical actuating performance with finite deformation is considered for the shape memory polymers and their composites ...
