Hysteresis and competition between disorder and crystallization in sheared and vibrated granular flow
Karen E. Daniels, Robert P. Behringer
Experiments on spherical particles in a 3D Couette cell vibrated from below and sheared from above show a hysteretic freezing/melting transition. Under sufficient vibration a cryst…
Slow Drag in 2D Granular Media
Junfei Geng, R. P. Behringer
We study the drag force experienced by an object slowly moving at constant velocity through a 2D granular material consisting of bidisperse disks. The drag force is dominated by fo…
Elastic Energy, Fluctuations and Temperature for Granular Materials
Lou Kondic, R. P. Behringer
We probe, using a model system, elastic and kinetic energies for sheared granular materials. For large enough (pressure/Young's modulus) and (kinetic energy de…
Memory in 2D heap experiments
Junfei Geng, Emily Longhi, R. P. Behringer +1
The measurement of force distributions in sandpiles provides a useful way to test concepts and models of the way forces propagate within noncohesive granular materials. Recent theo…
