[Question #689486]: Relationship between JCF contact law parametres and particle size
New question #689486 on Yade:
I have a question about parameter calibration, indeed I have a model in rock mass media generated by random size spheres.
just in the first step, in which I try to have a stable assembly of spheres, I put the values for tensile strength and cohesion of materials in the way that sphere particles remain just without movement under imposed cohesion between particles.
but I see when the particle size changes (new range of sphere sizes), I lose this preliminary stable condition and for each particle size range I should find new values for the parameters.
I would like to know how one can find the approximate values for these parameters to have just a stable condition in the model (not with very high magnitude), or how these values can be related to the size of particles?
Thanks a lot
Take care of yourself
