WebThis paper is a continuation of our previous work [1] on the modeling of the stress distribution in deep two-dimensional granular heaps or “wedges”. We amend the previous treatment of symmetric heaps and consider asymmetric heaps or “berms”, with one face at the angle of repose. WebThese angles are related to the internal friction of the material and its resistance to failure [7]. Critical angles have been extensively studied in previous studies [8–12] to characterize the stability of heaps of particles and most of the works were related to the characteristics and dynamics of avalanches [10,13–16].
WebWe study the dependence of the angle on the presence of walls and find an exponential decay on the distance between the walls. Modification of the granular fabric close to the surface changes the static angle of repose and the effect can still be noted after several inclinations of the cell indicating the existence of a memory effect.
