We briefly review the elastic properties of granular materials, as explored in numerical studies of simple model materials by the “discrete element method” (DEM). Elastic or quasielastic responses are obtained as stable contact networks are probe

We present a compact, linearized theory for the quasi-static deformation of elastic materials whose stored energy depends on the first two gradients of the displacement (second-grade elastic materials). The theory targets two main issues: (1) the mec

A method recently proposed for the computational modeling of backward erosion piping is applied for the numerical back-analysis of some pioneering experimental tests on physical models of cofferdams performed by Marsland (1953).

International audience; We report on a numerical experiment by which we investigated the propagation of an erosion pipe in a water saturated granular soil. The simulation was performed with a two-dimensional implementation of the coupling between the

A granular soil REV located on the upstream side of the erosion pipe front is modelled numerically, at the grain scale, by coupling the Discrete Element Method (DEM) with the Lattice Boltzmann Method (LBM) for the representation of the solid and flui

A preliminary discrete numerical model of a REV at the front region of an erosion pipe in a cohesive granular soil is briefly presented. The results reported herein refer to a simulation carried out by coupling the Discrete Element Method (DEM) with

Use of the Discrete Element Method (DEM) to simulate the asymptotic elastic behaviours of bituminous mixtures (low-temperature-high-frequency or high-temperature-low-frequency) is investigated. Aggregates are represented in the numerical specimen by

We discuss the microstructural origin of stress tensors for granular materials in the context of “non simple” continuum models, of the micropolar and of the second-gradient type. Stress tensors are looked upon as generalised forces in the sense o
