Philip Eisenlohr 21cad32137 # new interface for Abaqus
# IO has some additional functionality for Abaqus parsing
# ping pong scheme in FE interface now similar (and more human understandable) in both versions
# mesh has better splitting of different tasks, plus operation on database whenever possible
# FEsolver as new global var to indicate FEM solver type
# computation mode reshuffling: 6 is now Marc special case of recycling...

Philip Eisenlohr 02602144d2 can now be executed from different directories...but will operate on "its" one 2009-10-12 14:18:54 +00:00
Luc Hantcherli 3f41b271fb The new dislocation model is now implemented in constitutive_dislotwin.f90
(seems to run fine, but still under investigation)

Christoph Kords 4ff497e5ba mesh_build_sharedElems does not need an input argument anymore 2009-10-08 09:23:15 +00:00
Philip Eisenlohr e7247551f0 changed "build_sharedElements" to use (then existing) internal element data structure instead of reading again from the input file. The data structure is already established by "build_elements"... 2009-10-08 09:01:59 +00:00

Christoph Kords 9b3a59646a constitutive_nonlocal
- take orientation gradients into account when calculating dislocation stress and dislocation fluxes
- hard coded value for nu
- changed kinetics (parameter G0 is currently defined as a parameter, needs to be read from material.config)
- added some output statements

constitutive: 
- some functions and subroutines needed additional input variables for passing to constitutive_nonlocal 

crystallite:
- some functions and subroutines needed additional input variables for passing to constitutive
- call microstructure with current temperature, Fp, Fe, not "sub0" values
- show number of IPs, that are "onTrack" instead of those not "onTrack"
- calculate Fe at beginning of substep, since we need it for state preguess

Franz Roters c5865bb7ec corrected calculation of dTdLp 2009-10-02 06:40:12 +00:00
Christoph Kords c67412c36b added missing constitutive outputs for nonlocal law 2009-10-01 16:31:06 +00:00
Christoph Kords b09b2b17f3 convergence of state in crystallite is now tested as follows:
(state < relevant state) or (residuum < relative tolerance * state)
since the relevant value for the state variables depend on their nature and can vary by large scales (e.g. volume fraction: 1e-10, dislocation density: 1e5) it is not possible to set a unique value. instead the constitutive law has to decide what is relevant. therefore, all constitutive laws now read in parameters from the material.config that determine the values for relevantState [@luc: in dislobased law relevant State is for the moment generally set to 1e-200, so no additional parameters necessary in material.config. if you also want this feature, we can still implement it, no big deal]

- added sanity checks in constitutive_nonlocal.f90

- corrected coordinate transformation for backstress calculation in constitutive_nonlocal.f90

- corrected equations for evolution of dipole dislocation densities (athermal annihilation and formation by glide)

Denny Tjahjanto 5f7e5b8409 homogenization_RGC.f90
<< correction for a very stupid mistake. replacing stress P with the absolute value of stress abs(P) during convergence check. it should work upon deep-drawing.

Denny Tjahjanto 3ea17dd2fd CPFEM.f90 >>> A very small, not important thing.
homogenization.f90 and crystallite.f90 >>> Correction in the algorithm to count the iteration distribution (for better statistics).

material.config and numerics.config >>> more collection of parameters.
2009-08-28 15:05:14 +00:00
Christoph Kords f27d66a9ae constitutive_nonlocal:
- dipole dislocations with evolution

crystallite.f90:
- collect state uses subdt and subTstar0_v
- in nonlocal modus: set all crystallites to broken if one is not on track anymore after either stress integration or state update
- constitutive_microstructure is now called inside state update and not in integrate_stress anymore

material.config:
- new parameter for nonlocal constitution

CPFEM.f90:
- age Tstar after increment was finished
2009-08-28 13:50:47 +00:00
Denny Tjahjanto 644265381e mpie_cpfem_marc.f90 >>> changing the compilation sequence of modules: numerics.f90 and IO.f90 move up, while math.f90 down.
IO.f90 >>> adding "inRad" instead of using inRad from math.f90 module, since math.f90 module is now below IO.f90.

numerics.f90 >>> now can read the parameter "fixed_seed" from numerics.config. this parameter is used to set a pseudo-random number generator/fixed seeding. default value is 0 (zero), which will give fully random number.

math.f90 >> adding a possibility to fix the seeding (i.e., pseudo random number)

numerics.config >>> add a new parameter: "fixed_seed"

Denny Tjahjanto b25396374a homogenization_RGC.f90 >>> adding some lines, mostly for debugging purpose. no critical change.
constitutive_phenopowerlaw.f90 >>> adding new parameter: constitutive_phenopowerlaw_w0_slip, i.e., the hardening rate exponent.
homogenization.f90 >>> most important change is to add an if-else statement (line 379-380) to switch crystallite_requeted = .false. for already converged material point iteration (el/ip). the rest of the changes are cosmetics and debugging stuffs.
crystallite.f90 >>> similar to homogenization.f90, the most important change is to add additional if-else statement (line 574) in the jacobian (perturbation) loop. now the jacobian calculation will only be performed when crystallite_requested = .true.. the rest is only cosmetic.

Christoph Kords 1dbd0865db constitutive_nonlocal.f90
- completed postResults output function
- connecting vector of neighboring material points is mapped to intermediate configuration of my neighbor

crystallite.f90
- zero out dotState only when crystallite is non-finished
- set nonfinished flag to false if crystallite is not on Track after state update
- in updateState: set onTrack flag to false if encounter NaN
- removed some old debugging outputs and added others

homogenization.f90
- in debugging mode now telling when a cutback happens
2009-08-24 08:16:01 +00:00
Franz Roters 387195e036 that was tooo quick, now it works hopefully 2009-08-13 13:32:17 +00:00

Denny Tjahjanto cafc39b183 replaces Nast with Nreps in hybridIA
formerly, if the number of orientations requested was (far) less than the number of nonzero bins in the texture representation, you only got a subset of low phi1 values..! (that is the top corner in Euler space -- Hi Bing ;-) )

Franz Roters 6171361c7e terminallyIll was missing in the use statement 2009-08-12 08:10:28 +00:00
Christoph Kords 8ed3ddc03b now with first draft of nonlocal constitutive law
debugging memory leak closed
debugging counters corrected

center of gravity stored in mesh

state updated is now split into a collecting loop and an execution

updateState and updateTemperature fill sequentially separate logicals and evaluate afterwards to converged

added 3x3 transposition function, norm for 3x1 matrix and 33x3 matrix multiplication in math

non-converged crystallite triggers materialpoint cutback (used to respond elastically)

non-converged materialpoint raises terminal illness which in turn renders whole FE increment useless by means of odd stress/stiffness and thus waits for FE cutback

Philip Eisenlohr f337847f35 quite some changes:
# non-greedy memory allocation
# generation of outputConstitutive to allow for script-based T16 extraction
# exchange of phenomenological by more general phenopowerlaw
# lattice is based on slip and twin families which can be treated as individual entities (switched on/off, separate hardening, etc.)
# nicer debugging output
# changed some error/warning codes
# plus potentially some minor additional brushes here and there
