Shape Memory Polymer FEM Ansys

Hello everyone,

I hope to find an answer to my problem in this forum.

I'm working on the finite element model of a SMP in order to predict the recovery shape after heating. I'm in trouble about the material properties of this kind of polymer. I run tensile stress test, DMA and TMA in order to characterise the material. However I didn't succeed to write the good command in Ansys to get a shape memory effect.

Does anyone of you has knowledges about SMP ?

 

Thank you very much,

Michel
