摘要：

We use a site-site model to describe non-sphericity of particles composing a granular media. Specific effects of grain non-sphericity on the angle of repose are investigated. We report evidence indicating the possible existence of a shape-roughness threshold for grains: below it angles of repose are essentially the same as those obtained for spherical grain; above it there are pronounced changes on the angle of repose and it is possible to find rather large piles of grains.
