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 …

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 …

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 …

There is a simple and general experimental protocol to generate slow granular flows that
exhibit wide shear zones, qualitatively different from the narrow shear bands that are usually …

Flows of granular media down a rough inclined plane demonstrate a number of nonlocal
phenomena. We apply the recently proposed nonlocal granular fluidity model to this …

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 …

We show that the yielding transition in granular media displays second-order critical-point
scaling behavior. We carry out discrete element simulations in the low-inertial-number limit …

Developing a unified theory to describe granular matter, which can behave like either solid
or fluid, is one of the grand challenges in modern science. This is mainly because the …

We computationally study the behavior of the diffusion coefficient D in granular flows of
monodisperse and bidisperse particles spanning regions of relatively high and low shear …

This paper presents a two-dimensional SPH model designed to simulate free-surface flows
of dense granular materials. Smoothed particle hydrodynamics (SPH) is a mesh-free …
