CPFEM.f90 contains the following modifications:
...
-Temperature is now defined as a CPFEM_Temperature, and filled for each new call of CPFEM_general according the value output by MARC
-constitutive_Microstructure(state_new,CPFEM_Temperature,grain,CPFEM_in,cp_en) is used in the state loop and before entering in the stress loop. This subroutine computes all parameters,arrays or matrices required from the state, i.e. forest or parallel or mobile dislocation densities from the statistically stored dislocation densities. Its definition is made in module constitutive.
2007-10-16 08:33:59 +00:00
ab0fddf518
Module crystal contains a so-called interaction type matrix for each crystal structure. This matrix helps for computing the hardening matrix in case of a phenomenological constitutive or the dislocation interaction intensity matrix in case of a dislocation-based constitutive.
...
Definition can be discuss.
Corresponding changes should be carried on constitutive.f90
