This is a major update.

I restructured the subroutine in view of non local constitutive models.
ATTENTION OpenMP parallelization does not work with this version, needs some more work.
ATTENTION CPFEM_GIA8.f90 is not addopted to the new scheme and will NOT work, should actually be renamed CPFEM_RGC.f90 ;-)
I removed crystallite.f90, the routines are now in CPFEM_*.f90.
I removed the marc2005 interface routine since it is outdated.

New version of constitutive_dislo.f90, where some dangerous spots were reformulated.
...
PROBLEM: [001] in tension does not have a symmetrical change of shape, which is definitely not good at all. I checked my implementation and I really do not see any errors. Could someone check it out? Can it comes from the numerical integration?
2008-11-07 16:34:29 +00:00
6e13ed0566
I will proceed step by step.
...
constitutive_dislo.f90 contains a modified version of Anxin's dislocation based model. As far as tested it, I consider it now error free. Mechanical twinning is NOT implemented YET.
mattex.mpie file is modified in accordance with the changes in constitutive_dislo.f90
It would be a great help if someone else can check the implementation. I may have overseen something.
