in kinetics: non schmid stresses only influence peierls mechanism, but not solid solution hardening; as a result the derivative of the velocity with respect to the resolved stress has to be split into a Schmid and a non-Schmid part

3fcc00910c
fixed bug that occured under marc (and abaqus?) with openmp:
...
"lastLovl" (for marc) and "lastStep" (for abaqus) have to be global module variables in FEsolving.f90 instead of local variables in the respective DAMASK_* files; otherwise they are initialized with zero each time hypela2/umat is called.

nonSchmid behavior now ready to use for bcc with phenopowerlaw and nonlocal constitutive model.

plain mode (no ping pong) now seems to work for marc, further testing needed

regular sequence of computation modes is
inc 0: 1,1,1,…
inc 1: 0,0,0,…
7,1,1,…
0,0,0,…
1,1,1,…
and so on
after a cutback the computation modes follow as
inc 5: 8,0,0,…
1,1,1,…
0,0,0,…
1,1,1,…

Changed order of blocks associated with different tasks:

backup jacobian

changes on convergence tolerances of AL and Polarisation, switched back to immediate correction of stress bc but only when last two average stresses are close to each other (cosine decay)
2013-07-30 15:32:55 +00:00
03d8f14a98
introduced dynamics for high strain rate simulations. so far only works for materials with homogeneous density. the density is read in as an optional argument in the load file using the keyword 'den' or 'density'. if density > 0 then inertial terms are added to the stress equilibrium. an implicit euler time discretisation is used to calculate the inertial terms.
...
dynamic problems are length scale dependent so make sure the geometry size is meaningful (1 m^3 or N m^3 for example is too big for a RVE!).
not specifying a density (density = 0) will perform a quasi static simulation as before.
2013-07-26 16:25:37 +00:00

decoupled compatibility/equilibrium calculation from stress BC correction. needs more iteration for mildly contrasted materials, but there the basic scheme is better suited anyway. but now converges better for highly contrasted VEs

Fixed bug in math rotations: passive and active rotations were not clearly distinguished and partly mixed up; yet, luckily, only resulted in wrong output of euler angles.
...
Now fixed with following convention:
Rotation conversions do not switch implicitly from active to passive or vice versa EXCEPT when converting to or from any "Euler" type (Euler angles or Euler axis/angles). Those functions expect a passive rotation as input if converting to Euler type and return a passive rotation if converting from Euler type.
