Topology of Force Networks in Granular Media under Impact
Melody X. Lim, Robert P. Behringer
We investigate the evolution of the force network in experimental systems of two-dimensional granular materials under impact. We use the first Betti number, , and persistence…
Orientation, Flow, and Clogging in a Two-Dimensional Hopper: Ellipses vs. Disks
Junyao Tang, Robert P. Behringer
Two-dimensional (2D) hopper flow of disks has been extensively studied. Here, we investigate hopper flow of ellipses with aspect ratio , and we contrast that behavior to the…
The Jamming point street-lamp in the world of granular media
Corentin Coulais, Robert P. Behringer, Olivier Dauchot
The Jamming of soft spheres at zero temperature, the J-point, has been extensively studied both numerically and theoretically and can now be considered as a safe location in the sp…
Fluctuations in Shear-Jammed States: A Statistical Ensemble Approach
Dapeng Bi, Jie Zhang, R. P. Behringer +1
Granular matter exists out of thermal equilibrium, i.e. it is athermal. While conventional equilibrium statistical mechanics is not useful for characterizing granular materials, th…
Granular Impact Model as an Energy-Depth Relation
Abram H. Clark, Robert P. Behringer
Velocity-squared drag forces are common in describing an object moving through a granular material. The resulting force law is a nonlinear differential equation, and closed-form so…
Contacts Dynamics Reveals Widom Lines for Jamming
C. Coulais, R. P. Behringer, O. Dauchot
We experimentally study the vicinity of the Jamming transition by investigating the statics and the dynamics of the contact network of an horizontally shaken bi-disperse packing of…
