We perform numerical simulations of a two-dimensional frictional granular system under oscillatory shear confined by constant pressure. found that the undergoes dilatancy as strain increases. confirmed compaction also takes place at an intermediate amplitude for small mutual friction coefficient between particles. depends on confinement pressure while little

Abstract Different particle properties, such as shape, size, surface roughness, and constituent material stiffness, affect the mechanical behavior of coarse-grained soils. Systematic investigation individual effects these properties requires careful control over other which is a pervasive challenge in investigations with natural The rapid advance 3D printing technology provides ability to produ...
