Abstract The whole process of concrete slump experiment was simulated with Particle Flow Code 3 Dimensions (PFC3D) software based on discrete element simulation. simulation results are in good agreement the macroscopic obtained from field experiments, indicating that use PFC for had feasibility have a observation speed and direction particles slump.

This work develops a continuum-based combined finite–discrete element method (FDEM) in the framework of explicit finite conjunction with fracture algorithms. To account for complex fracturing processes, both shear failure and tensile criteria are implemented. Furthermore, to investigate effect different algorithms on accuracy computational efficiency simulations, inter-element intra-element dev...
