Stress-Strain diagrams for non-convex particles

Stress-Strain diagrams for non-convex particles

While most granular materials in nature and technology consist of non-convex particles, the majority of discrete element (DEM) codes are still only able to cope with convex particles, due to the complexity of the computational geometry and the occurrence of multiple contacts. We have reengineered a...
