A study of grains flow in a two dimensional hopper using particle tracking and photoelastic methods is presented in this article. An intermittent network of contact forces consisting of force chains and arches is observed. This network is responsible for fluctuations in the average vertical velocity. The magnitude of these fluctuations depends on the hopper’s geometry, and it quickly reduces for large...
A cylindrical cavity in a noncohesive granular medium will collapse under gravity, leaving a circular crater in the surface of the material. We study this process through experiment and numerical modeling. Experimentally, we determine the shape and dimensions of craters formed by the collapse of a cylindrical cavity in a bed of small glass beads. Using a depth-averaged continuum model with cylindrical...
