I just read other replies... Well, pick your way! ;-)

Hi Luc,
The CohesiveFrictional contact law is very general, it includes
normal, shear, bending, and torsion components (bending and torsion
are purely elastic for now, it is no big deal to add a threshold for
failure). You could start with this law and add missing features, or
perhaps derive a new law from this one if you need much more
sophistications.

Hi Anton,
Thank you for your answer. So, if I understand well, the RPM is quite
similar to the CohesiveFrictionalContactLaw? I don't grab all the
idea. Could you please be a bit more illustrative?

The idea is to create some particles "connected" (cohesive) with
each other, if they are close to each other on the first stage of
simulation.
After that, if cohesive particle positions are too far or too
close to each other, destruction occurs. And particles become like
a simple granular media.

Hi all,
I currently start a new project on rock slope stability in
open pit mines. I now know YADE for a while and I am sure it
can be a great tool for that and I want to prove it to my
supervisor.
I have seen that some work has been done on rock modelling (I
saw that a RockParticleModel class has been introduced in the
new release 0.20). I am still trying to understand what is
written on that files but, honestly, I am a bit lost when I
compare to what I did with granular materials
(CapillaryCohesiveLaw ;) ).
The idea, for the moment, is to model some kind of a fractured
rock mass within which particles can interact either in
clusters with a cohesive behaviour (rock blocks) or between
clusters with a contacting law representative of a rock joint
(maybe with an artefact to control the roughness). In
addition, maybe it would be useful to deal with spheres such
as they are a part of a lattice with no collision detection
and no inertia or something like that (?).
Maybe some of you have already think about it and I would be
grateful for any advices and suggestions.
Regards
Luc
