On the angles of dry granular heaps
Web1 de mai. de 2024 · Moreover, for fine and dry granular material with a small angle of repose and a particle size <5 μm, no defined relationship exists between the repose and … 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.

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. WebWe repeated similar measurements of for different filling heights of the glass box and no significant differences were found at the laboratory scale we were working with. Repose angle by avalanche (θR) and maximum angle of stability (θM): The granular packing is prepared by completely filling up the box with grains, as depicted in figure 2(d).
