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…

Enlightening force chains: a review of photoelasticimetry in granular matter
Aghil Abed Zadeh, Jonathan Barés, Theodore A. Brzinski +10
A photoelastic material will reveal its internal stresses when observed through polarizing filters. This eye-catching property has enlightened our understanding of granular materia…

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…
