摘要：

Detailed particle models by taking into account the material grain structure explicitly consider the material randomness, including a size limiter for damage localization. A VGMC3D contact model is presented that considers the polyhedral particle shape in an approximate way. The VGCM3D flexible contact model is validated against known experimental data on a granite rock, namely triaxial tests and Brazilian tests.
