Thermoviscoelastic shape memory behavior for epoxy-shape memory polymer
Smart Materials and Structures, 2014There are various applications for shape memory polymer (SMP) in the smart materials and structures field due to its large recoverable strain and controllable driving method. The mechanical shape memory deformation mechanism is so obscure that many samples and test schemes have to be tried in order to verify a final design proposal for a smart ...

Modeling the shape memory effect of shape memory polymer
SPIE Proceedings, 2009Dynamic mechanical analysis (DMA) tests are conducted on the styrene-based shape memory polymer (SMP) to investigate its state transition behaviors. Tensile tests at various constant temperatures are carried out to reveal the stressstrain- temperature relationship of the styrene-based SMP.
