Hi Robert,

Thanks for the answer on the Aeq quantity, I suspected something like
that but was unsure...

Well, you've asked my second question, I also wonder why in the
formulation of this contact law he chose to use the minimum of the two.
Maybe the CPM mat was meant to be used for materials with an homogeneous
size distribution in the particles ? Or to model granular material at a
scale where particles do not represent material particles, and thus
might not need a specific size distribution. Then the difference of
radius between two given spheres could be neglected ?

However, since in this formulation the li~ equals Aeq over li, I am
right in assuming that the li distance corresponds to ri ?

Cheers,
Manon
