We review the general aspects of the concept of temperature in equilibrium and non-
equilibrium statistical mechanics. Although temperature is an old and well-established …

Computer Simulations belong to the most important methods for the theoretical investigation
of granular materials. The present book is intended to serve as an introduction to the field …

We perform a dimension analysis for colliding viscoelastic spheres to show that the
coefficient of normal restitution ε depends on the impact velocity g as ε= 1− γ 1 g 1/5+ γ 2 g …

Steady state dynamics of clustering, long-range order, and inelastic collapse are
experimentally observed in vertically shaken granular monolayers. At large vibration …

" Granular Gases" are diluted many-particle systems in which the mean free path of the
particles is much larger than the typical particle size, and where particle collisions occur …

Abstract Direct Monte Carlo simulations of the Enskog-Boltzmann equation for a spatially
uniform system of smooth inelastic spheres are performed. In order to reach a steady state …

The nonequilibrium steady state of a granular fluid, driven by a random external force, is
demonstrated to exhibit long-range correlations, which behave as∼ 1/r in three and∼ ln …

The theory of homogeneously driven granular gases of hard particles predicts that the
stationary state is characterized by a velocity distribution function with overpopulated high …

When a granular material experiences strong forcing, as may be the case, eg, for coal or
gravel flowing down a chute or snow (or rocks) avalanching down a mountain slope, the …

The inelastic hard sphere model of granular material is simple, easily accessible to theory
and simulation, and captures much of the physics of granular media. It has three drawbacks …
