Hi,

I need help in how to find a constitutive model for shape memory polymer and their composites, and subsequently writing a UMAT subroutine to use with ABAQUS.

Asimple example and/or step by step tutorial to find a model will be very helpful. I have in hand some papers about the modeling of the SMP, however they are very complicated and using high level continuum mechanics which I am not professional with.

Regards,

Wessam
