....(5) For the dimensionless tangential dissipation we use j t = fl t = p m 12 k t = 0:01 throughout this paper. A more extensive discussion on the implementation of tangential forces can be found in [55, 70] Alternative formulations for force laws of polygonal particles have been given in [46, 48, 79, 81]. 3 From the micro to a macro description In the previous section, the microscopic point of view was introduced, as used in the discrete element method. Particles are viewed as independent entities which interact when they come in contact. In this framework, the knowledge of the forces at each ....

....forces. These complex particles, or grains , are collections of simpler basic particles stuck together with permanent bonds made of dissipative springs. The idea is that the complicated macroscopic laws of friction will arise dynamically from the many microscopic collisions of these rough grains [5]. There is interest in the results for both two and three dimensions. These piles form and grow dynamically, and hence there is an ever changing spatial distribution of clusters of particles; load balance is clearly one of the key issues for any parallel implementation. 3 Methodology There was ....
