Jamming I: A volume function for jammed matter

Song, Chaoming; Wang, Ping; Jin, Yuliang; Makse, Hernán A. - In: Physica A: Statistical Mechanics and its Applications 389 (2010) 21, pp. 4497-4509

We introduce a “Hamiltonian”-like function, called the volume function, indispensable to describe the ensemble of … jammed matter such as granular materials and emulsions from a geometrical point of view. The volume function represents the … available volume of each particle in the jammed systems. At the microscopic level, we show that the volume function is the …

Jamming in two-dimensional packings

Meyer, Sam; Song, Chaoming; Jin, Yuliang; Wang, Kun; … - In: Physica A: Statistical Mechanics and its Applications 389 (2010) 22, pp. 5137-5144

We investigate the existence of random close and random loose packing limits in two-dimensional packings of monodisperse hard disks. A statistical mechanics approach–based on several approximations to predict the probability distribution of volumes–suggests the existence of the limiting...

Fundamental problems in statistical physics of jammed packings

Edwards, S.F.; Grinev, D.V.; Brujić, J. - In: Physica A: Statistical Mechanics and its Applications 330 (2003) 1, pp. 61-76

For packed i.e., “jammed”, hard and rough objects kinetic energy is a minor and ignorable quantity, as is elastic strain. Hence in the static case, the stress equations need supplementing by “missing equations” depending solely on configurations. A different pathway of analysis is the...

Transmission of stress in granular materials as a problem of statistical mechanics

Edwards, S.F.; Grinev, D.V. - In: Physica A: Statistical Mechanics and its Applications 302 (2001) 1, pp. 162-186

We consider the problem of stress transmission in granular materials. We formulate the simplest statically determinate problem of stress transmission through a static granular material. This is the case when grains are rigid and have an average coordination number of z̄=d+1. Under this...

GRANULAR MEDIA AS A PHYSICS PROBLEM

EDWARDS, S. F.; GRINEV, D. V. - In: Advances in Complex Systems (ACS) 04 (2001) 04, pp. 451-467

Although there is a vast engineering literature for granular materials, as a subject for physicists it has seen great growth in recent years. This is because, when stripped down to the fundamental problem, it is quite novel, and demands a rethink of the kind of laws familiar elsewhere in...
