| Abstract: |
| Based on the hypoplastic model with 2nd P-K stress rate,a hypoplastic model for granular materials exhibiting particle crushing is presented by adopting an experiential curve between void and a wide range of mean effective pressure,including those sufficient to cause particle crushing.The modes of strain localization and loading carry capability of granular materials are investigated under two cases, (1)considering particle crushing (2) without considering particle crushing; numerical results illustrate the capability and performance of presented model in modeling the effects of particle crushing on deformation of granular materials. |
