From force distribution to average coordination number in frictional granular matter
Ping Wang, Chaoming Song, Christopher Briscoe +2
We study the joint probability distribution of normal and tangential frictional forces in jammed granular media, , for various friction coefficient , especially w…
Distribution of volumes and coordination number in jammed matter: mesoscopic ensemble
Ping Wang, Chaoming Song, Yuliang Jin +2
We investigate the distribution of the volume and coordination number associated to each particle in a jammed packing of monodisperse hard sphere using the mesoscopic ensemble deve…
Jamming II: Edwards' statistical mechanics of random packings of hard spheres
Ping Wang, Chaoming Song, Yuliang Jin +1
The problem of finding the most efficient way to pack spheres has an illustrious history, dating back to the crystalline arrays conjectured by Kepler and the random geometries expl…
Entropy of jammed matter
Christopher Briscoe, Chaoming Song, Ping Wang +1
We investigate the nature of randomness in disordered packings of frictional spheres. We calculate the entropy of 3D packings through the force and volume ensemble of jammed matter…
Jamming I: A volume function for jammed matter
Chaoming Song, Ping Wang, Yuliang Jin +1
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 geom…
Particle dynamics and effective temperature of jammed granular matter in a slowly sheared 3D Couette cell
Ping Wang, Chaoming Song, Christopher Briscoe +1
We report experimental measurements of particle dynamics on slowly sheared granular matter in a three-dimensional (3D) Couette cell. A closely-packed ensemble of transparent spheri…
