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 …

Granular materials are ubiquitous in our daily lives. While they have been the subject of
intensive engineering research for centuries, in the last two decades granular matter has …

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 …

We present results on a series of two-dimensional atomistic computer simulations of
amorphous systems subjected to simple shear in the athermal, quasistatic limit. The …

We investigate the flowing behavior of dense suspensions of noncolloidal particles, by
coupling macroscopic rheometric experiments and local velocity and concentration …

We model a sheared disordered solid using the theory of shear transformation zones (STZs).
In this mean-field continuum model the density of zones is governed by an effective …

Using discrete simulations, we investigate the behavior of a model granular material within
an annular shear cell. Specifically, two-dimensional assemblies of disks are placed between …

We study the emergence of shear thickening in dense suspensions of non-Brownian
particles. We combine local velocity and concentration measurements using magnetic …

Using the results of recent numerical simulations, we extend an existing kinetic theory for
dense flows of identical, nearly elastic, frictionless spheres to identical, very dissipative …

We introduce a simple phenomenological modification to the hydrodynamic equations for
dense flows of identical, frictionless, inelastic disks and show that the resulting theory …
