Paul Schröder is still having a problem:
Thank you for your answer Jan,
as far as I can see now, the core question is answered with it. However, I
would still be interested in the further, whether I can also make a distinction
in static and sliding friction? Is such a distinction possible with a standard
material model?
If someone would like to learn from this question in the future, I summarize my
knowledge here:
> 2) How it behaves in actual simulation
In order to examine the particle contact in the script belonging to the
question, I have inserted the code suggested by Jan accordingly at my example
within the function "Statemaschine()" after the definition of "Krit4":
###
if Krit4:
intr = O.interactions[Partikelmenge0+0,Platte1groesse0+4]
tanfa = intr.phys.tangensOfFrictionAngle
print("actually assigned value:", tanfa)
###
Then I also noticed that further settings the smaller friction value of both
contact partners is taken over. To change that, I have applied the suggested
"MatchMaker" according to [7]. The appropriate formulation, which is
supplemented into the definition of the engines, I adapted for it as follows. I
have added here the friction value leading steel-steel, even if this is not
needed in my simulation.
###
[Ip2_FrictMat_FrictMat_FrictPhys(frictAngle=MatchMaker(matches=((idVersuchsgut,
idStempelPlatte, atan(0.75)),(idVersuchsgut, idVersuchsgut,
.65),(idStempelPlatte, idStempelPlatte, atan(0.12)))))],
