Complex behavior models
(plasticity, cracks, visco elascticity) face some theoretical
difficulties for the determination of the behavior law at the continuous
scale. When homogenization fails to give the right behavior law, a
solution is to simulate the material at a meso scale in order to
simulate directly a set of discrete properties that are responsible of
the macroscopic behavior. The discrete element model has been developed
for granular material. The proposed set shows how this method is
capable to solve the problem of complex behavior that are linked to
discrete meso scale effects.
