Can we calculate strain energy function based on stress-strain?
Sat, 2014-12-06 00:02 - yw5aj
Hi all,
I do know that we can get 1-st PK stress P from taking derivative of the strain energy function W with respect to deformation gradient F. However, would there be any way to back the W out from integrating P with F, or something similar?
Thanks in advance,
Shawn
