We review flows of dense cohesionless granular materials, with a special focus on the
question of constitutive equations. We first discuss the existence of a dense flow regime …

Sand, rice, sugar, snow, cement... Although ubiquitous in our daily lives, granular media still
challenge engineers and fascinate researchers. This book provides the state-of-the-art of the …

Granular flows are omnipresent in nature and industrial processes, but their rheological
properties such as apparent friction and packing fraction are still elusive when inertial …

The statement of the title is shown by numerical simulation of homogeneously sheared
assemblies of frictionless, nearly rigid beads in the quasistatic limit. Results coincide for …

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 …

Using discrete numerical simulations, we have studied the flow down a rough inclined plane
of a bidisperse assembly of frictional cohesionless disks. Our study focuses on steady …

By means of extensive contact dynamics simulations, we analyzed the effect of particle size
distribution (PSD) on the strength and microstructure of sheared granular materials …

The shear strength of dense granular flows is generally described by an effective friction
coefficient, ratio of shear to normal stress, as a function of the inertial number I. However, this …
