Microscopic Reversibility and Emergent Elasticity in Ultrastable Granular Systems
Yiqiu Zhao, Yuchen Zhao, Dong Wang +3
In a recent paper [Phys. Rev. X 12, 031021], we reported experimental observations of ``ultrastable'' states in a shear-jammed granular system subjected to small-amplitude cyclic s…
Ultra-stable shear jammed granular material
Yiqiu Zhao, Yuchen Zhao, Dong Wang +3
Dry granular materials such as sand, gravel, pills, or agricultural grains, can become rigid when compressed or sheared. At low density, one can distort the shape of a container of…
Two approaches to quantification of force networks in particulate systems
Rituparna Basak, C. Manuel Carlevaro, Ryan Kozlowski +6
The interactions between particles in particulate systems are organized in `force networks', mesoscale features that bridge between the particle scale and the scale of the system a…
Transparent Experiments: Releasing Data from Mechanical Tests on Three Dimensional Hydrogel Sphere Packings
Jonathan Barés, Nicolas Brodu, Hu Zheng +1
We describe here experiments on the mechanics of hydrogel particle packings from the Behringer lab, performed between 2012 and 2015. These experiments quantify the evolution of all…
Sheared Amorphous Packings Display Two Separate Particle Transport Mechanisms
Dong Wang, Joshua A. Dijksman, Jonathan Bares +2
Shearing granular materials induces non-affine displacements. Such non-affine displacements have been studied extensively, and are known to correlate with plasticity and other mech…
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…
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…
`Sinking' in a bed of grains activated by shearing
Hu Zheng, Dong Wang, Jonathan Barés +1
We show how a weak force, , enables intruder motion through dense granular materials subject to external mechanical excitations, in the present case stepwise shearing. A force a…
Force and Mass Dynamics in Non-Newtonian Suspensions
Melody X. Lim, Jonathan Barés, Hu Zheng +1
Above a certain solid fraction, dense granular suspensions in water exhibit non-Newtonian behavior, including impact-activated solidification. Although it has been suggested that s…
Shear Jamming in Granular Experiments without Basal Friction
Hu Zheng, Joshua A. Dijksman, Robert P. Behringer
Jammed states of frictional granular systems can be induced by shear strain at densities below the isostatic jamming density (). It remains unclear, however, how much friction…
