Granular materials do not always flow homogeneously like fluids when submitted to external
stress, but often form rigid regions that are separated by narrow shear bands where the …

Recent experiments and numerical simulations of dry granular flows suggest that a simple
rheological description in terms of a friction coefficient varying both with shear rate and …

Understanding the rheology of granular assemblies is important for natural and engineering
systems, but the relationship between inter-particle friction (or microscopic friction) and …

Recent experiments and numerical simulations of dry granular flows suggest that a simple
rheological description in terms of a shear rate dependent friction coefficient, may be …

The aim of this paper is to examine the possibility of a simple fluid‐mechanics treatment of
rapid dense granular flows. In other words, we examine whether the constitutive equation …

It is well known that heterogeneous granular flows exhibit collisional, dense and creep
regimes that can coexist in space. How to correctly predict and control such complex …

Friction plays an important role in the behavior of flowing granular media. The effective
friction coefficient is a description of shear strength in both slow and rapid flows of these …

We perform extensive molecular dynamics simulations of two-dimensional frictionless
granular materials to determine whether these systems can be characterized by a single …

The steady-state shear rheology of granular materials is investigated in slow quasistatic and
inertial flows. The effect of gravity (thus the local pressure) and the often-neglected contact …

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 …
