Yun Jo Ro b3814020f3 added slip and twin systems for hcp lattice structure
added straightforward 48x48 interaction matrix
2008-08-06 14:48:11 +00:00
Philip Eisenlohr 7faaa8532c this provides adapted functionality to go with the sequential wrapper.
moved recording of temperature, ffn, and ffn1 into case of computation
mode 1,2 to be directly used in the subsequent (and now FE sequential)
call to MaterialPoint.
2008-08-01 07:58:59 +00:00
Philip Eisenlohr db69217ce1 removed computation mode 3 (collect) such that now every cycle will
compute with either mode=1 (new inc) or mode=2

Philip Eisenlohr 10358fc1f0 (hopefully) improved the cutbacking scheme somewhat. introduced a bunch

Luc Hantcherli 7453a18b42 in lattice:
- add slip-twin interaction type matrix
2008-06-17 14:42:45 +00:00
Luc Hantcherli 434ac7f06e In dislo:
- model for stacking fault energy computation w.r.t temperature and orientation
- classical thermodynamical approach to twin nucleation (delta_E)
- rename some parameters

In crystallite:
- add msg='ok', even if components in consistent tangent are not re-computed
- allow for pseudo-convergence in the outer-loop (case of slow convergence of dislocation densities)

in mattex:
- add new parameters
2008-06-17 14:40:46 +00:00
Franz Roters 2472de77c2 OpenMP seems to work now
watch out for critical sections
write and matmul statements need to be marked accordingly!!!

Philip Eisenlohr 6921c57c7d rev 225 had a small syntax error... 2008-06-17 11:54:34 +00:00
Philip Eisenlohr 3676b453ca added two more element types (157 and 136) 2008-06-17 09:11:54 +00:00
Philip Eisenlohr 5834a2965d fixed bug in mesh_build_sharedElems which so far counted nodes in
distorted elements twice -- part of this problem has already been fixed
with revision 182 but then only in getNodeElemDimensions.

Philip Eisenlohr 51e596c81d small polishing to be compatible with NAG compiler (basis for automatic differentiation) 2008-04-29 12:18:17 +00:00
Luc Hantcherli 9626c25bfb crystallite: restoration of last known good Lp_guess
CPFEM_Taylor: exit whenever cutback limit exceeded
2008-04-28 16:04:08 +00:00
Philip Eisenlohr cdb2dd8808 crystallite:
added full check whether residuum in inner loop is NaN
SingleCrystallite now takes/stores Lp guess

CPFEM_Taylor (missing in GIA!!):
former fully plastic guess for Lp has been exchanged by keeping the last converged Lp (global array CPFEM_Lp) to serve as new best guess for the next time step. This speeds up the inner loop of TimeIntegration.

Luc Hantcherli fa2d6b9b6d Make use of average consistent tangent dPdF_bar to fill eventual holes in the individual dPdF of one orientation (during consistent tangent calculation) 2008-04-11 13:04:25 +00:00

Denny Tjahjanto 9d2ce61698 A revision for CPFEM_Taylor.f90. 2008-04-10 11:22:17 +00:00
Franz Roters d2312e81ff deleted CFPFEM.f90 and crystal.f90 from repository
adopted mattex.mpie to use lattice_structure  instead of crystal_structure
2008-04-09 15:35:16 +00:00
Denny Tjahjanto 12dfbaf6b4 # separated CPFEM_Crystallite from CPFEM. Now in separate module crystallite.f90 as "SingleCrystallite"
# improved SingleCrystallite to advance by true cutbacking (instead of improving guess and integrating always from t_0)
# module "crystal" renamed to "lattice" together with its prefix for variables
# extension of "computationMode" to deal with cutbacks (CPFEM_general).
# cutback and new inc detection for MARC is based on common block variable cptim (and inc), not incsub anymore!
# generalized GrainInterAction as new homogenization scheme

# two symbolic links are required: constitutive.f90 and CPFEM.f90

Philip Eisenlohr 3640a48095 changed element type mapping to be performed right after input file
parsing. mesh_element(2,e) now contains INTERNAL type index -- no
subsequent mapping necessary anymore!
