Dynamics of a grain-scale intruder in a two-dimensional granular medium with and without basal friction
Ryan Kozlowski, C. Manuel Carlevaro, Karen E. Daniels +5
We report on a series of experiments in which a grain-sized intruder is pushed by a spring through a 2D granular material comprised of photoelastic disks in a Couette geometry. We…
Dynamics of oblique impact in a photoelastic granular medium
Cacey Stevens Bester, Noah Cox, Hu Zheng +1
When a solid projectile impacts a granular target, it experiences a drag force and abruptly comes to rest as its momentum transfers to the grains. An empirical drag force law succe…
Shear jammed, fragile, and steady states in homogeneously strained granular materials
Yiqiu Zhao, Jonathan Barés, Hu Zheng +2
We study the jamming phase diagram of sheared granular material using a novel Couette shear set-up with multi-ring bottom. The set-up uses small basal friction forces to apply a vo…
Jamming transition in non-spherical particle systems: pentagons vs. disks
Yiqiu Zhao, Jonathan Barés, Hu Zheng +4
We investigate the jamming transition in a quasi-2D granular material composed of regular pentagons or disks subjected to quasistatic uniaxial compression. We report six major find…
