Understanding and modelling the dynamic behaviour of particulate systems has been a
major research focus worldwide for many years. Discrete particle simulation plays an …

Characterization and prediction of the “flowability” of powders are of paramount importance
in many industries. However, our understanding of the flow of powders like cement or flour is …

Using molecular dynamic simulations, we investigate the characteristics of dense flows of
model cohesive grains. We describe their rheological behaviour and its origin at the scale of …

Molecular dynamics simulations are used to investigate the structure and mechanical
properties of a simple two-dimensional model of a cohesive granular material. Intergranular …

Recent progresses in understanding the behavior of dense granular flows are presented.
After presenting a bulk rheology of granular materials, I focus on the new developments to …

In this study, a three-dimensional (3D) numerical investigation of axisymmetric collapse of
granular columns has been conducted using the discrete element method (DEM). The …

Continuum mechanics relies on the fundamental notion of a mesoscopic volume “element”
in which properties averaged over discrete particles obey deterministic relationships. Recent …

Field studies suggest that bedrock incision by granular flows may be the primary process
cutting valleys in steep, unglaciated landscapes. An expression has been proposed for …

The quasistatic behavior of a simple two-dimensional model of a cohesive powder under
isotropic loads is investigated by discrete element simulations. We ignore contact plasticity …

We simulate dense assemblies of frictional spherical grains in steady shear flow under
controlled normal stress P in the presence of a small amount of an interstitial liquid, which …
