Pratheek Shanthraj 35f9e91e73 some corrections to the damage models 2015-03-06 13:12:32 +00:00
Pratheek Shanthraj bbb5ff6ae9 changes related to intermediate configuration kinematics:
- switched Fi and Li from state variables to crystallite variables

- Lp and Li are now work conjugate with the corresponding mandel stresses defined in their respective configuration

- T, Lp and Li need to return tangents wrt Fi arising from the convection of the material frame due to Fi

- Updated analytic jacobian to take into account tangents wrt Fi

- Updated Lp and Li residual jacobians to take into account tangents wrt Fi
