RISShape representation of axisymmetrical, non-spherical particles in discrete element simulation using multi-element model particles
A new method of representing non-spherical, smooth-surfaced, axi-symmetrical
particles in discrete element (DE) simulation using model particles comprising overlapping
spheres of arbitrary size whose centres ...
A new probabilistic approach for predicting particle crushing in one dimensional compression of granular soil
On the Stress-Force-Fabric relationship in anisotropic granular materials
, in which the elongated particles are arranged directionally. In this paper, reliability of SFF relationship is examined for both isotropic and anisotropic samples. To this aim, Discrete Element Method (DEM) is applied to compare the simulated behavior...
Microdynamic analysis of oscillating transportation of particles
Transportation of granular material using an oscillating plate is studied based on the results generated by Discrete Element Method (DEM). The objective is to present a numerical simulation method to model the motion of granular material consisting...
Discrete element modeling of inherently anisotropic granular assemblies with polygonal particles
tests using the discrete element method (DEM). Particle shape is considered to be irregular convex-polygonal. The effect of inherent anisotropy is investigated by following the evolution of mobilized shear strength and volume change during loading...
Mechanical Behavior Modeling of Sand-Rubber Chips Mixtures Using Discrete Element Method (DEM)
of this paper is to study the effect of adding different rubber portions on the global engineering properties of the mixtures. This study is performed by using Discrete Element Method (DEM). The simulations showed that adding rubber up to a particular fraction...
The Effect of Particle Crushing and Confining Pressure on the Mechanical Behavior of Granular Materials Using DEM
One of the important problems in geotechnical engineering is the evolution of granular soil behavior as a result of particle breakage. By using Discrete Element Method (DEM), a model is established to simulate the breakage of two...
