Shape-memory Polymer Deformation (IMAGE) Georgia Institute of Technology Research News Caption Inside a thermo-mechanical test frame, a shape-memory polymer fractures as it stretches past its deformation limit. This testing allows the researchers to determine the maximum possible shape change from the permanent to temporary shape and vice versa.
