Re: Starting a new project on rock slope stability

 

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
