In geotechnical applications the success of the discrete element method (DEM) in simulating fundamental aspects of soil behaviour has increased the interest in applications for direct simulation of engineering scale boundary value problems (BVP’s).

Rheophysics of dense granular materials : Discrete simulation of plane shear flows

Autor: da Cruz, Frederic, Emam, Sacha, Prochnow, Michael, Roux, Jean-Noel, Chevoir, Francois

We study the steady plane shear flow of a dense assembly of frictional, inelastic disks using discrete simulation and prescribing the pressure and the shear rate. We show that, in the limit of rigid grains, the shear state is determined by a single d

International audience; Discrete Fracture Network (DFN) is a modeling framework for fractured rocks. The core element is the description of geological medium as a network of discrete fractures that can be either generated from statistical distributio
