Thermoviscoplastic Modeling and Testing of Shape Memory Polymer Based Self-Healing Syntactic Foam Programmed at Glassy Temperature

Wei Xu, Guoqiang Li
Journal: Journal of Applied Mechanics
Publisher: ASME
Article Type: Research Papers
J. Appl. Mech. November 2011, 78(6): 061017.
https://doi.org/10.1115/1.4004554
Published Online: August 25, 2011
...Wei Xu; Guoqiang Li Traditionally, programming of shape memory polymer (SMP) material requires initial heating above the glass transition temperature (T g ), subsequent cooling below T g and removal of the applied load. Therefore, the shape fixity process is inconvenient for some applications. Most...
