Intruder in a two-dimensional granular system: statics and dynamics of force networks in an experimental system experiencing stick-slip dynamics
R. Basak, R. Kozlowski, L. A. Pugnaloni +4
In quasi-two-dimensional experiments with photoelastic particles confined to an annular region, an intruder constrained to move in a circular path halfway between the annular walls…
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…
Stress propagation in locally loaded packings of disks and pentagons
Ryan Kozlowski, Hu Zheng, Karen E. Daniels +1
The mechanical strength and flow of granular materials can depend strongly on the shapes of individual grains. We report quantitative results obtained from photoelasticimetry exper…
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…
Yielding, Rigidity, and Tensile Stress in Sheared Columns of Hexapod Granules
Yuchen Zhao, Jonathan Barés, Joshua E. S. Socolar
Granular packings of non-convex or elongated particles can form free-standing structures like walls or arches. For some particle shapes, such as staples, the rigidity arises from i…
