Abstract: A mesh-free smoothed particle hydrodynamics (SPH) method is developed to simulate the failure of heterogeneous materials under different strain rates on 3D compression specimens. An elasto-plastic damage model is adopted to describe the pressure-sensitive strength behavior of the heterogeneous materials. Numerical simulations are performed for the constructed 3D artificial granite specimens. Results demonstrate that the proposed 3D modeling method can better resemble the rock microstructure and heterogeneity and it can be further used in other applications.
