This review focuses on how the modeling of dense granular media has advanced over the
last 15 years. The jum**-off point of our review is the μ (I) rheology for dry granular flow …

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 …

Dense granular materials display a complicated set of flow properties, which differentiate
them from ordinary fluids. Despite their ubiquity, no model has been developed that captures …

One challenge of today's research is the realistic simulation of granular materials, like sand
or powders, consisting of millions of particles. In this article, the discrete element method …

Shear bands, localized regions where shear flows concentrate, form in many complex fluids
under a wide range of circumstances. In this review, we outline the main mechanisms that …

Cohesive powders have widely different bulk behavior due to their peculiar interactions. We
use discrete element simulations to investigate the effect of contact cohesion on the steady …

Shear induced alignment of elongated particles is studied experimentally and numerically.
We show that shear alignment of ensembles of macroscopic particles is comparable even …

We establish that the rheological curve of dry granular media is nonmonotonic, both in the
presence and absence of external mechanical agitations. In the presence of weak …

We study the rheology of dry and wet granular materials in the steady quasistatic regime
using the discrete element method in a split-bottom ring shear cell with focus on the …

We fluidize a granular medium through localized stirring and probe the mechanical
response of quiescent regions far away from the main flow. In these regions the material …
