When a system jams, it undergoes a transition from a flowing to a rigid state. Despite this
important change in the dynamics, the internal structure of the system remains disordered in …

Amorphous materials as diverse as foams, emulsions, colloidal suspensions and granular
media can jam into a rigid, disordered state where they withstand finite shear stresses …

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 …

Hard spheres are ubiquitous in condensed matter: they have been used as models for
liquids, crystals, colloidal systems, granular systems, and powders. Packings of hard …

In 1989, Sir Sam Edwards made the visionary proposition to treat jammed granular materials
using a volume ensemble of equiprobable jammed states in analogy to thermal equilibrium …

The arrangements of particles and forces in granular materials have a complex organization
on multiple spatial scales that range from local structures to mesoscale and system-wide …

Dense suspensions of particles are relevant to many applications and are a key platform for
develo** a fundamental physics of out-of-equilibrium systems. They present challenging …

The role of the friction coefficient, μ, on the jamming properties of disordered, particle
packings is studied using computer simulations. Compressed, soft-sphere packings are …

A constitutive model is developed for the complex rheology of rate-independent granular
materials. The closures for the pressure and the macroscopic friction coefficient are linked to …

Using sedimentation to obtain precisely controlled packings of noncohesive spheres, we
find that the volume fraction ϕ RLP of the loosest mechanically stable packing is in an …
