abbae76c51
instantaneous jumps in the state by constitutive_deltaState are now incorporated for all state integrators. still they (should) not influence the result, since all constitutive laws simply return zero for the deltaState
2012-05-17 15:25:21 +00:00
351c2c6e65
deltaState depends on the current state, no the state at the beginning of the timestep

2012-05-16 15:35:14 +00:00
84d4652a07
all constitutive modules now contain a new function "deltaState", which in the future allows to have an instantaneous and incremental change of the state (additional to the rate based evolution with dotState).

Dead dislocations are treated the same as mobile dislocations for the flux part though they do not contribute to slip. By that the pileup of dead dislocations is able to diminish with time (kinetics are the same as for the glide part; this is not correct but gives valuable results). Also remobilization of dead dislocations at neighbor is taken into account for flux.

d62eddc0cd
corrected kinetics law and changed parameters. For solid solution hardening there are 3 parameters: the activation energy, the concentration of obstacles that determines the activation length and meanfreepath, and the obstacle size that determines the activation volume. For the Peierls mechanism there is: the width of doublekinks that determines the activation volume and the Peierls stress for edge and screw.
...
Still testing needed to check whether the current formulation makes sense or not.
2012-02-03 12:50:54 +00:00
bbf4f25898
renamed subroutine "mesh_marc_get_mpieOptions" to "mesh_get_damaskOptions" which is now also used for abaqus and spectral input files. The only available option so far is "periodic", which allows for periodic fluxes in the specified direction. Examples for usage (add the following lines to the respective input file, in case of spectral file this goes into the header):
...
- periodicity in x and z direction for marc:
$damask periodic x z
- periodicity in y direction for abaqus:
**damask periodic y
- periodicity in x and y direction for spectral:
periodic y x

added new math function "math_deviatoric33" which returns the deviatoric part of a 3x3 tensor
...
renamed some math functions, so that we have a universal naming scheme: for matrix multiplications use an "x" (e.g. math_mul33x3); don't use the "x" to describe the shape of the tensor that the function is applied to (e.g. math_invert33 instead of math_invert3x3)

e5407894b5
Reworked kinetics. Now there is a universal law which can be used for both fcc and bcc (and probably even hcp). It mainly consists of an athermal forest cutting part , solid solution and peierls as thermally activated processes, and viscous glide. Therefore, lots of new parameters in the material.config. Not sure yet if the values make sense though.
...
Also renamed some of the old parameters.
Unknown constitutive output raises error.

dislocation stress does not add to stress field anymore, but is only available as constitutive output for purposes of postprocessing. instead, we now use a backstress term (which is added to the resolved shear stress) that depends on the gradient of excess density on the same slip system.

Math inversion used to return zero (math_inv3x3) or error (math_invert3x3) for negative determinant. Now checking whether the absolute(!) value of the determinant is close to zero to avoid singularities, negative determinants are very well allowed.

constitutive_nonlocal:
...
dislocation velocities are stored in the state, so we actually now have three "parts" of the state, the basic states that are updated by "constitutive_dotState" come first, then the dependent states that are calculated by "constitutive_microstructure" follow, and finally we have a last part reserved for other variables that just use the memory reserved by the state array and are updated somewhere else.
constitutive:
LpAndItsTangent does not need the full state, but only the local state, so changed that at least for the nonlocal constitutive law
2011-11-04 13:12:17 +00:00
9d1bc584d0
corrected stress integration scheme: now use norm(Lpresiduum) as a target function for Armijo's rule instead of whole tensor Lp; also corrected the guess for the improvement in Lp
2011-11-04 12:57:12 +00:00
ca3d21a3b6
Depending on which state integrator one uses for the stiffness calculation, the initial state has to be chosen accordingly: e.g. for FPI choose last converged state, but for explicit RK choose converged state from start of increment (in case of explicit euler no state integration at all, but only stress integration). For this purpose we also need to remember "Fe" which now follows the cutbacking procedure as it is used for "Fp".
2011-11-04 12:44:50 +00:00

restart write is on per default
restart read is switched on by using --restart or -r INT where INT gives step at which the calculation should restart
setting INT to a value <1 will turn restart write off

Introduced environment variable DAMASK_ROOT.
...
It is set in the DAMASK root folder by running damask_env.sh
Much needed in the testing routines so far (try ./testing/run_tests.py)
damask_env.sh could also trigger other scripts to get to a working setup after fresh checkout. For example it could run
./processing/setup/setup_processing.py
./code/setup/setup_code.py
if it finds that we have a fresh checkout.

ip volume is now based on the determinant of F. "mesh_ipVolume" represents the initial volume and is multiplied with det(F) wherever the current volume is needed. Since this works for all solver types, the "volume" output in crystallite is now also correct for spectral method and abaqus.

corrected calculation of stress BC condition. Depending on given BC, the stiffness matrix is reduced and than inversed. Then it is filled with zeros and used for the calculation of the correct change of deformation gradient. All calculation is done using dP/dF

Calculation of current ip volumes now working. Crystallite output also reflects current grain volume, not reference volume. However, this is only available for Marc. Abaqus and spectral method still return the reference ip volume. The ip coordinates though are correctly updated for all solver types.

Stress integration now uses Armijo rule to find an appropriate correction of Lp: decreases step in case that residuum does not improve significantly, accelerates as usual in case of good convergence. This turned out to improve convergence behavior.

* internal stress calculation now considers dead dislocations always at the interface, not at the center of the IP volume; used to merge them together with "normal" dislocations for stress calculation.
...
* dislocation flux is blocked if we encounter a sign change in the resolved shear stress from the central ip to the neighbor
* do not set density to zero if below certain threshold; this creates an artificial sink term

restarting now works with Abaqus (standard, cannot test explicit due to lack of license)
...
you have to specify the job you are restarting from in the job description (cae), if you prepare your input file by hand this is the first line after *Heading
example: if the first job was using Oldjob.inp the first entry in the job description needs to be Oldjob (without the .inp)
as for Marc restart works only from last converged increment, i.e. ther restart writing should be specified like this:
*retsart, write, frequency=1, overlay
Overlay is not essential but saves a lot of disk space and as stated before you can only restart from the last converged increment anyway

changed input of loadcase. Now fdot (time derivative) can be used instead of velocity gradient. Velocity gradient needs to have each line fully or not at all defined, as for other loadcases the stress BCs are not known in advance. Also added the possibility to keep guessing along trajectory of former loadcase.
