Modeling of heterogeneous materials and media is a problem of fundamental importance to
a wide class of phenomena and systems, ranging from condensed matter physics, soft …

Granular materials consist of macroscopic grains, interacting via contact forces, and
unaffected by thermal fluctuations. They are one of a class systems that undergo jamming, ie …

Jamming is a ubiquitous phenomenon that appears in many soft matter systems, including
granular materials, foams, colloidal suspensions, emulsions, polymers, and cells—when …

We investigate the structural, vibrational, and mechanical properties of jammed packings of
deformable particles with shape degrees of freedom in three dimensions (3D). Each 3D …

Jamming is an athermal transition between flowing and rigid states in amorphous systems
such as granular matter, colloidal suspensions, complex fluids and cells. The jamming …

We study the jamming phase diagram of sheared granular material using a novel Couette
shear setup with a multiring bottom. The setup uses small basal friction forces to apply a …

Amorphous sphere packings have been intensely investigated to understand mechanical
and flow behaviour of dense granular matter and to explore universal aspects of the …

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 …

Estimates of the onset of sediment motion are integral for flood protection and river
management but are often highly inaccurate. The critical shear stress (τ* c) for grain …

Understanding the way disordered particle packings transition between jammed (rigid) and
unjammed (fluid) states is of both great practical importance and strong fundamental …
