摘要：

A three-dimensional grain model based on the concept of particles assembly using cohesive bonds is presented. A script is developed to generate polyhedral grains, by assembling tetrahedral particles using cohesive bonds. A series of single grain crushing simulations is performed, and the effect of the intra-granular cohesion on the grain's strength is studied. Oedometric compression tests are simulated. The effect of grain breakage on the macroscopical behaviour is evaluated.
