3D SPH modeling of heterogeneous materials failure under dynamic loads

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 mater...
