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 …

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 …

Shear thickening is the increase of the apparent viscosity as shear rate or shear stress
increases. This phenomenon is pronounced in concentrated (dense) suspensions of both …

One of the outstanding problems in understanding the behavior of intermediate-to-silicic
magmatic systems is the mechanism (s) by which large volumes of crystal-poor rhyolite can …

Shear thickening is a phenomenon in which the viscosity of a suspension increases with
increasing stress or shear rate, sometimes in a discontinuous fashion. While the …

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 …

Partially molten rocks, often called a mush, are examples of a hydrogranular mixture where
the dynamics are controlled by both fluid and crystal‐crystal interactions. An obstacle to …

Systems of randomly packed, macroscopic elements, from jammed spherical grains to
tangled long filaments, represent a broad class of disordered meta-materials with a wide …

In this work, discrete element method (DEM) is used to study the effect of particle size and
aspect ratio on packing structure of fine ellipsoids. It shows that porosity and coordination …

The packing and flow of aspherical frictional particles are studied using discrete element
simulations. Particles are superballs with shape| x| s+| y| s+| z| s= 1 that varies from sphere …
