Mechanical Simulation of Granular Materials by DEM Analysis
A study of four constitutive contact models employed in discrete element analysis is presented. Most discrete element simulations employ simple contact models due to computational time constraints. However, few works are available in literature which evaluates the suitability of these simple models to simulate DEM applications. The influence of more complex models on bulk behavior is examined t...

متن کاملIncremental response of granular materials: DEM results
We systematically investigate the incremental response of various equilibrium states of dense 2D model granular materials, along the biaxial compression path (σ11 < σ22, σ12 = 0). Stress increments are applied in arbitrary directions in 3dimensional stress space (σ11,σ22,σ12). In states with stable contact networks we compute the stiffness matrix and the elastic moduli, and separate elastic and...
متن کاملAnisotropic elastic theory of preloaded granular media
A macroscopic elastic description of stresses in static, preloaded granular media is derived systematically from the microscopic elasticity of individual inter-grain contacts. The assumed preloaded state and friction at contacts ensure that the network of inter-grain contacts is not altered by small perturbations. The texture of this network, set by the preparation of the system, is encoded in ...
متن کاملThe Influence of Contact Friction on the Breakage Behavior of Brittle Granular Materials using DEM
In this study, a numerical triaxial compression test was carried out to investigate the influence of contact friction on the breakage behavior of brittle granular materials using the 3D discrete element method. An commercial software named Particle Flow Code 3D (PFC3D) was applied to undertake these simulations. The cubic numerical model was 30mm wide, 30mm long, and 30mm high, and contained 56...
