Dynamics at the Angle of Repose: Jamming, Bistability, and Collapse
When a sandpile relaxes under vibration, it is known that its measured angle of repose is bistable in a range of values bounded by a material-dependent maximal angle of stability; thus, at the same angle of repose, a sandpile can be stationary or avalanching, depending on its history. In the nearly jammed slow dynamical regime, sandpile collapse to a zero angle of repose can also occur, as a ra...
متن کاملThe jamming transition of Granular Media
A statistical mechanical approach to granular material is proposed. Using lattice models from standard Statistical Mechanics and results from a mean field replica approach we find a jamming transition in granular media closely related to the glass transition in super-cooled liquids. These models reproduce the logarithmic relaxation in granular compaction and reversible-irreversible lines, in ag...
متن کاملMaximum Angle of Stability of a Wet Granular Pile
Anyone who has built a sandcastle recognizes that the addition of liquid to granular materials increases their stability. However, measurements of this increased stability often conflict with theory and with each other [1–7]. A friction-based Mohr-Coulomb model has been developed [3, 8]. However, it distinguishes between granular friction and inter-particle friction, and uses the former without...
متن کاملJamming transition in granular systems.
Recent simulations have predicted that near jamming for collections of spherical particles, there will be a discontinuous increase in the mean contact number Z at a critical volume fraction phi(c). Above phi(c), Z and the pressure P are predicted to increase as power laws in phi-phi(c). In experiments using photoelastic disks we corroborate a rapid increase in Z at phi(c) and power-law behavior...
