Jamming is not just cool any more

Article Abstract:

Cates and colleagues have proposed that jammed systems differ fundamentally from ordinary solids, such that if the direction of applied stress alters only slightly, the jam will break up. Their model does not consider the jammed system as an elastic body, and in the case of an extended material, such as a sandpile, bypassing the strain throughout the pile of particles, means there is a link between different parts of the stress tensor. If the particles deform that material can respond elastically to small loads.

Structural signature of jamming in granular media

Article Abstract:

Evidence for structural signature is demonstrated by measuring the contact-force distribution between particles during shearing. The measurements provide a determination of a granular temperature that is the counterpart in granular systems to the glass-transition temperature in liquids.

Signatures of granular microstructure in dense shear flows

Article Abstract:

A study of granular materials and their microstructures is presented with reference to dense shear flows. The use of spectroscopy reveals the significance of the variation of the speed of these flows in the particles.
