Vibrated granular matter
Granular matter is defined as a large collection of particles the size of which is larger than one micron so that Brownian motion is negligible. Its behavior has been studied at least since the days of Charles-Augustin de Coulomb (1736-1806), who originally stated his law of friction for granular …

Energy propagation in jammed granular matter
The systems built from dense granular materials are very important due to their relevance to a number of technological and other fields. However, they are difficult to study in particular due to a lack of accurate continuum description. In this work, studies on these systems are presented using …

On the Compaction of Granular Matter; Continuum and Discrete Numerical Modelling
Granular materials are ubiquitous in nature and industry alike, ranging from assemblies of large rocks to the finest of powders. Nonetheless, compared to fluids and solids, our understanding of granular materials remains limited, because the macroscopic mechanical behaviour of a granular material …

Density relaxation of granular matter through Monte Carlo and granular dynamics simulations
Granular materials are the principal ingredients of the industrial complex involved with the handling and processing of bulk solids including pharmaceuticals, chemicals, agricultural and mining materials. Despite the enormous importance of these materials in society, their behavior is not …

Using avalanche statistics to forecast failure in models of earthquake faults and magnets
… variety of dynamical systems, such as magnets, granular matter, earthquake faults, neuronal networks, and of course the classic example of snow flows on mountains. By studying the statistics of avalanche sizes, we can understand the response of such systems to external driving forces, as well …

Reversibility, memory formation and collective rotations in dense granular media
Granular matter is a broad term that describes materials comprised of macroscopic grains. Granular material has unique properties that can mimic either a solid- or fluid-like system and has macroscopic behaviors such as segregation, shear- jamming, reversibility, and compaction. The finite size of …

Defects and Rearrangements in Disordered Solids
… of materials, including glasses, polymers, granular matter, dense colloids, and gels. There is currently no constitutive equation based on microscopic observables that describes these materials. Given the prevalence and usefulness of these materials, we derive tools to aid our understanding …

Order and Asymmetry in Jammed Systems
<p>Granular matter is composed of particles that are big enough that thermal effects may be neglected. We studied both granular flow and granular statics using numerical simulation. In granular flow, we simulated 2D granular flow in a hopper. A hopper is a container with an opening at the bottom. …

Developing a mechanistic model for flow through a perforated plate with application to screening of particulate materials
… based understanding of the behaviour of the granular system. To go beyond the current state-of-the-art in screen modelling requires a clear understanding of the particle motion along a dynamic (vibrating) inclined plane. Central to this understanding is the notion that granular systems …

Understanding bulk behavior of particulate materials from particle scale simulations
Particulate materials play an increasingly significant role in various industries, such as pharmaceutical manufacturing, food, mining, and civil engineering. The objective of this research is to better understand bulk behaviors of particulate materials from particle scale simulations. Packing …
