Re: R: Re: Compaction_phase/Triax
I didn't want to say that I can control porosity via stress, but that they are
not independent (am I wrong anyway?).
You are not wrong, the dependency is just very small (as long as you
don't modelize bubble-gum packings or other sorts of very soft material).
So, having a specific particle size
distribution, the contact stiffnesses, the angle of friction, is it possible to
get a specific value of porosity for the specimen? How can I do it with Yade?
You need some trial and error, playing with friction.
A more sophisticated way would be to decrease friction with time, until
you reach the good porosity. It allows a very precise control of final
porosity, but I didn't implement it in Yade yet, because I don't need
very precise porosities for now.
Sorry if I continue on this point, but I am a little bit confused on it.
No worries. :)
