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

some cosmetics...
2009-07-23 13:33:53 +00:00
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

Example of material.config, delivering the required information for the new version of constitutive_dislobased
2009-07-14 11:31:06 +00:00
ce515beb39
THIS IS A MAJOR UPDATE
...
The different blocks required for the twinning model are now implemented (I guess correctly...)
Keywords in the material.config are changed. Since the flow rule for twin systems remains under investigation, this part is susceptible to further changes.
2009-07-14 11:26:52 +00:00

Corrected definition of vector n and d per deformation system; n is the system plane normal and d the corresponding direction

restructured the repository: renamed trunk into code, moved documentation one directory up, therefore you can now checkout either code or documentation only if you like
2009-06-25 07:17:59 +00:00
06ed8c8177

660dce0f09
now safe to request values from config-parsing which are not present.
...
3rd and up value of key "xyz" would return "0" or "0.0" in this example:
xyz 1.234 4.321
2009-06-19 07:09:39 +00:00

move operation into "Code" part of documentation
2009-06-19 07:02:57 +00:00
ef8b672a00
numerics.config is now optional; if this file does not exist in the working directory, standard values from numerics.f90 are used; either way the output file tells which values were taken.
...
added some output to the init subroutines of debug.f90, FEsolving.f90, lattice.f90, material.f90 and mesh.f90.
2009-06-18 14:28:02 +00:00
904ea78ac5
Tstar_v is now restored at different stages of cutbacking; we need this because preguess of state relies on consistent Tstar_v
2009-06-16 09:03:30 +00:00
ada92a9b74
added a new module called numerics.f90 which reads in all numerical "parameters" from the file numerics.config (also being added). From now on this file has to be located in the working directory of the FEM-model and has to contain all necessary parameters.

in crystallite_stressAndItsTangent we now update the state first (explicit integration) and then integrate the stress (implicit integration)
...
also inside the stress integration, it is now possible to define the frequency of the Jacobian update oin the LpLoop through iJacoLpResiduum. The frequency of the Jacobian update for the stiffness in the crystallite loop is controlled by the parameter iJacoStiffness.
also updated the corresponding stuctograms in the documentation
