Christoph Kords ec377a6e8e removed obsolete "dead zone" scaling 2013-08-21 08:39:43 +00:00
Christoph Kords f706ba3ff9 rearranged arguments of "constitutive_nonlocal_kinetics", got "tauTreshold" as argument, not complete state
don't call "constitutive_nonlocal_kinetics" twice for edges in case of nonSchmid behavior, but just call once and copy results from positive to negative edges
2013-08-21 07:55:34 +00:00
Christoph Kords 277972edbd "dv_dtau" argument in "constitutive_nonlocal_kinetics" not optional anymore
renamed "screwStressProjection" to "nonSchmidProjection"
2013-08-21 07:23:02 +00:00
Christoph Kords e909b825cc correction of hardening coefficients also enabled for bcc
for fcc: now applied to all hardening coefficients, not only hirth, lomer, and glissile

Martin Diehl c93373a4ac removed long lines 2013-08-08 19:33:21 +00:00
Christoph Kords f2d6703148 multiplication now sensitive of crystal structure, yet multiplication in bcc identical to fcc except for the contribution of edges which is completely dropped for bcc 2013-08-05 09:26:37 +00:00
Christoph Kords 813ed130b0 nonSchmid behavior now ready to use for bcc with phenopowerlaw and nonlocal constitutive model.
nonSchmid tensors according to Koester,Ma,Hartmaier,2012.
extended lattice_Sslip with non-Schmid tensors (the full non-symmetric tensors are required for the tangent and cannot be retrieved from the symmetrized Mandel notation)
2013-08-05 09:23:21 +00:00
Martin Diehl 40ace5c666 more documentation and parameters capitalization unified and using ipc in all modules (sometimes called gr)

Philip Eisenlohr fd8d85896a error msg in case of unknown keyword was not properly trimmed --> 64kB of spaces... 2013-06-27 16:41:00 +00:00
Philip Eisenlohr 98528f9a89 added possibility for multi-level inclusion of files in *.config and loadcase files.
include subfiles by stating

Christoph Kords daf89806b1 fixed bug in deltaState; used to lead to unpredictable values in accumulated shear, since deltaState was not defined at this state position 2013-06-11 21:03:23 +00:00
Martin Diehl 296a5040b9 fixed bug in initialization when reading in material.config.
Fortran does not short-circuit, e.g. (if a>0 .and. b(a) ==c) might cause an out-of-bounds error when a=-1 it'll try to access b(-1)!
2013-06-11 20:16:40 +00:00

Christoph Kords b559666436 replaced FE_maxNipNeighbors with mesh_maxNipNeighbors, which is sufficient for memory allocation, since this gives the maximum of neighbors in all cp elements 2013-05-23 17:46:21 +00:00
Christoph Kords 77e9b80a16 bug fix for calculation of fluxdensity and slipnormal/direction in constitutive_nonlocal_postResults: indices for Fe were missing 2013-05-23 14:52:57 +00:00

Christoph Kords 6fac7c347c fixed bug in constitutive_nonlocal_kinetics that was introduced in rev2088 along with the non-Schmid behavior: nonSchmid matrix of last slip system was used for all slip systems; led to extremely bad convergence due to flawed dLp_dT 2013-05-10 22:29:12 +00:00
Christoph Kords d9cc42daef slight change in flux formulation: no flux to neighbor, not only if there is a sign change in the velocity, but also if the neighboring velocity is exactly zero 2013-05-10 08:42:42 +00:00
Martin Diehl b2a3c9235b fixed some warnings issued by gfortran (type conversion, not needed use statements) 2013-05-08 09:23:47 +00:00
Christoph Kords 6e64b5c476 better not allow for deads to contribute to flux, since not clear at which interface they got stuck 2013-05-07 18:47:17 +00:00
Christoph Kords a7706090d2 neighborhood relations were screwed up for some elementtypes as of version 2318, might have caused segmentation faults with nonlocal model, now fixed 2013-04-22 13:35:35 +00:00

Christoph Kords 10e50bf41d improved accuracy of "accumulated shear": now added as a state variable, which facilitates integration (dotstate=shearrate); needs absolute tolerance value for state integration in material.config 2013-04-04 13:37:14 +00:00
Christoph Kords 3c25723139 - make sure that formerly blocked density is not able to move to neighbor until it is remobilized
- added some explicit indices instead of ":"
2013-04-03 16:29:48 +00:00
Christoph Kords 6d3f05b387 small changes in nonlocal constitutive model:
- make sure neighboring density is always greater equal zero
- no extra Bauschinger in postResults
2013-04-03 16:22:55 +00:00
Christoph Kords b8f8d66f82 total density used in backstress calculation now based on average of neighborhood
fixed small bug in state_init: random distribution of density was probably not working correctly, as some variables were not properly initialized
2013-03-27 13:04:01 +00:00
Christoph Kords 19655c2d92 significantRho check was flawed for dipole density 2013-03-25 17:36:04 +00:00
Franz Roters 02f092492e updated copyright header 2013-03-22 17:35:05 +00:00
Christoph Kords cee90bbdb3 simplified dislocation kinetics: dropped relativistic correction of velocity, since the infinite attack frequency already sets a limit for the velocity; dropped second; also dropped the correction term for backward jumps, since it was probably not meaningful 2013-03-21 12:52:29 +00:00
Pratheek Shanthraj 07ff1f7c93 reporting current time for most module inits 2013-02-25 16:34:59 +00:00
Philip Eisenlohr c1cf446774 parsing of material.config file now expects adequate number of (slip/twin) family entries according to given lattice type.
used to read up to maxN, but that caused unnecessary IO_warnings...
2013-02-14 22:24:55 +00:00
Martin Diehl f0b4281400 removed unused variables, added pure statements, and declared external functions as external (using gfortrans debug option) 2013-02-11 10:43:45 +00:00
Mahesh Balasubramaniam 362cbf3359 Made corresponding changes in the constitutive files and DAMASK_spectral_driver and interface files with respect to the changes made to IO.f90 2013-02-06 16:45:34 +00:00
