Mechanical Behaviour of Meso-Scale Structure at Critical State for Granular Soils
Abstract The macro- and meso-numerical simulations of biaxial tests for ideal granular samples with different initial densities were carried out using discrete element method. Loop structures, which are represented by voronoi polygons, were taken as the basic meso-mechanical unit of granular material by mesh-subdivision. The meso-mechanical characteristic at critical state for granular media was especially analyzed. The contact forces of side particles and inner sliding rates of same kinds of loops in granular samples with different initial densities have respectively reached critical state. From the mesoscopic point of view, critical state of granular media is the consequence of mutual transformation for higher-order loops and lower-order loops, the combined average and external manifestation of all loops.
