Force networks and elasticity in granular silos
John F. Wambaugh, Robert R. Hartley, Robert P. Behringer
We have made experimental observations of the force networks within a two-dimensional granular silo similar to the classical system of Janssen. Models like that of Janssen predict…
Response to perturbations for granular flow in a hopper
John F. Wambaugh, John V. Matthews, Pierre A. Gremaud +1
We experimentally investigate the response to perturbations of circular symmetry for dense granular flow inside a three-dimensional right-conical hopper. These experiments consist…
Simple models for granular force networks
John F. Wambaugh
A remarkable feature of static granular matter is the distribution of force along intricate networks. Even regular inter-particle contact networks produce wildly inhomogeneous forc…
Ratchet-Induced Segregation and Transport of Non-Spherical Grains
J. F. Wambaugh, C. Reichhardt, C. J. Olson
We consider through simulations the behavior of elongated grains on a vibrating ratchet-shaped base. We observe differences in layer velocity profile and in net grain velocity for…
Superconducting Fluxon Pumps and Lenses
J. F. Wambaugh, C. Reichhardt, C. J. Olson +2
We study stochastic transport of fluxons in superconductors by alternating current (AC) rectification. Our simulated system provides a fluxon pump, "lens", or fluxon "rectifier" be…
