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…
