It is already implemented and used for CohFric and derived class. There
is no difference between incremental and total for relative rotations,
only shear disp. can be incremental.
That is an implementation inside a constitutive law; unless someone will
use the cot&paste method, it is not generally useful. In my opinion,
therefore, that does not count really.
We both know the design is outdated and this code needs more love.
Still, it is fully functional in Yade 0.50, from QtGui using
https://www.yade-dem.org/sphinx/yade.wrapper.html#yade.wrapper.CohesiveTriaxialTest,
or from python using
https://www.yade-dem.org/sphinx/yade.wrapper.html#yade.wrapper.Law2_ScGeom_CohFrictPhys_ElasticPlastic
and others.
It's been used for years and has been validated many times, even by
third party (https://lists.launchpad.net/yade-dev/msg03067.html),
not like if anything had to be derived or implemented. So, I'd not
recommend the implementation of 6DOF from scratch, since for now we have
unexplained results even with the simpler 3DOF. At least, if one really
likes blind implementation from scratch, he should benchmark his code
vs. CohFrict law.
Putting curent code for moment law in the 6DOF framework will need a lot
of time (as for me, I spent enough to adapt it to changes and make a
functor out of it already, I'd rather focus on 3DOF and
scaleDisplacementT if I could). Janek said he might "clean" that code
eventually IIRC? (ping ;))
