Hi,
I need to use the 2nd Piola Kirchoff Stress (S) rather than the usual Cauchy stress i(sigma) in a general transport equation of a material. I was wondering if I need to replace the stress tensor (usually denoted by sigma) with S, or do I just write sigma in terms of S using the relationship that exists between S and sigma.
Thanks!
