Granular materials, like sand, powder or grains present intriguing phenomena. Vibration and
shearing can lead to convective motion and segregation. A variation of stress may cause …

Granular materials display a variety of behaviors that are in many ways different from those
of other substances. They cannot be easily classified as either solids or liquids. This has …

We report systematic measurements of the density of a vibrated granular material as a
function of time. Monodisperse spherical beads were confined to a cylindrical container and …

The objective of this paper is to identify a numerical method to simulate motion of a packed
or fluidized bed of fuel particles in combustion chambers, such as a grate furnace and a …

We present molecular dynamics simulations of granular material submitted to vibrations in a
two-dimensional system. We find various types of convection cells, due either to the …

The complementary use of computer simulations and analogue simulations to explore the
physics of multiparticle systems is demonstrated. Applications to problems of current interest …

Granular materials are an integral part of our everyday life. They are also the base material
for most industrial processing techniques. The highly dissipative nature of the particle …

In recent years, sand has become a paradigm of complexity in physics; despite its everyday
familiarity, it has come to typify what is increasingly regarded as a'new'state of matter …

The authors present an implementation of realistic static friction in molecular dynamics (MD)
simulations of granular particles. In their model, to break contact between two particles, one …

The field of granular physics has burgeoned since its development in the late 1980s, when
physicists first began to use statistical mechanics to study granular media. They are …
