Understanding and modelling the dynamic behaviour of particulate systems has been a
major research focus worldwide for many years. Discrete particle simulation plays an …

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 …

This introductory text develops the fundamental physics of the behavior of granular
materials. It covers the basic properties of flow, friction, and fluidization of uniform granular …

We have investigated the rise of a single large glass bead through a vibrated cylindrical
column of smaller particles and found that vibration-induced size separation in this geometry …

Most studies on granular physics have focused on dry granular media, with no liquids
between the grains. However, in geology and many real world applications (eg food …

颗粒物质是地球上存在最多, 最为人们所熟悉的物质类型之一. 大量颗粒组成的离散态物质体系
具有特别的性质和运动规律. 颗粒物质表现出许多不同于固, 液, 气物质的奇特现象和独特的运动 …

High-resolution images of the surface of asteroid Itokawa from the Hayabusa mission reveal
it to be covered with unconsolidated millimeter-sized and larger gravels. Locations and …

Vibrations in a granular material can spontaneously produce convection rolls reminiscent of
those seen in fluids. Magnetic resonance imaging provides a sensitive and noninvasive …

Starting from 2D experimental observations and using topological arguments, we search for
the set of stable positions when a large disk is raised step by step among a 2D array of small …

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 …
