Philip Eisenlohr 0dd99cb965 lattice: (re)introduced _symmetryType function to replace unsafe lookup array 
numerics: polishing

mpie_cpfem_marc: polishing

..powerlaw: aware of symmetryType function

crystallite: aware of symmetryType function, smaller leapfrog acceleration

IO: new warning 101

CPFEM: range of odd stress is now -1e15...+1e15, H_sym is used for stiffness

Christoph Kords fce7590c17 * now able to choose method for state integration (integrator and integratorStiffness in numerics.config); standard is "Fixed Point Iteration", which is basically the same as before; others available are "Explicit Euler", "AdaptiveEuler", "Classical Runge-Kutta" and "Runge-Kutta Cash-Karp" 
* now remembering stiffness similar to how we do it for Lp etc.; avoids undefined stiffness values for nonconverged stiffness calculation

* non-local stuff:
   * changed non-local kinetics (Gilman2002)
   * enforce zero shearrate for overall carrrier density below relevant density
   * enforce zero density for those states that become negative and were below relevant density before
   * dislocation velocity is not limited by V^(1/3) / dt anymore

Alankar Alankar 2cc7bc38d7 Fixed a missing ','. Assigned plane and direction names. 2010-10-01 06:32:44 +00:00
Philip Eisenlohr 1ae252c1ce altered hexagonal slip systems 
(needs comparison to former set, which is potentially wrong)
 2010-09-30 17:31:19 +00:00
Philip Eisenlohr b259fbd9c6 1) added distribution of leapfrog breaks 
2) lattice_symmetryType is now a function (former lookup array was buggy)
3) stricter check of state var values (>0!) and memory deallocation done

Philip Eisenlohr e4067f2d26 debugged zoo of rotation operations and transformations 
all angles now in radians

introduced a rudimentary check in math_init to complain (IO_error) about broken transformations (e.g. quat --> R --> quat)

Claudio Zambaldi 249042c2d3 New output can be requested from crystallite: 
(output) grainrotation
it gives the deviation from the initial grain orientation 
in axis-angle representation with the angle in degrees.

Franz Roters 9c63005c8f allow for longer pathes when openening files 
corrected error messages concerning file openening

Philip Eisenlohr 5d5e7eb8f8 corrected uncritical mix-up of Ntwin and Nslip in reshaping fcc interaction (slip--twin) 2009-10-21 13:41:09 +00:00
Philip Eisenlohr 4e98935287 changed lattice_interaction matrices to (other:me) notation 
fixed small mistake in hexagonal twin--slip interaction matrix

adopted above switched notation for hardening matrix calculation
shortened dotState by introducing dot_product notation
 2009-10-21 13:10:12 +00:00
Philip Eisenlohr e1586d5059 fixed (probably severe) bug in hexagonal twin system transformation into ortho-hexagonal coordinates. 
cleaning up of twin system nomenclature

introduced lookup mechanism  to calculate the twinning shears depending on the c/a ratio of the present structure (was [wrongly!!] hardcoded to Titanium)
 2009-10-20 16:13:25 +00:00
Philip Eisenlohr 974116808b fixed a potential memory leak for hexagonal structures. added some status output to constitutive_xx 2009-10-15 20:02:52 +00:00
Luc Hantcherli bb8a71557b Added comment on FCC different interaction types 
1 --> self
2 --> coplanar
3 --> collinear
4 --> Hirth locks
5 --> glissile junctions
6 --> Lomer locks

Denny Tjahjanto f70013ee9b lattice.f90: correction of typo from the last update (Philip) 2009-08-26 09:02:22 +00:00
Philip Eisenlohr 7720680f3a makeMe: some polishment 
lattice: found memory leak (lattice_interactionTwinSlip had wrong size) and added further commenting
 2009-08-26 07:28:43 +00:00
Luc Hantcherli 9bbde133a1 Updated constitutive_dislobased.90 and lattice.f90 according to the changes done in the previous release 
- introduction of system families
- analogous structure to constitutive_phenopowerlaw.f90
- interaction types 0-1 changed into 1-2
 2009-07-24 12:02:20 +00:00
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

Luc Hantcherli d3343ef795 Corrected definition of vector n and d per deformation system; n is the system plane normal and d the corresponding direction 2009-07-14 11:20:35 +00:00
Franz Roters a6ccfe2e44 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
