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…
Average outpouring velocity and flow rate of grains discharged from a tilted quasi-2D silo
Ryan Kozlowski, J. Carter Luketich, Elijah Oshatz +2
The flow of granular materials through constricted openings is important in many natural and industrial processes. These complex flows - featuring dense, dissipative flow in the bu…
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…
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…
Intruder in a two-dimensional granular system: Effects of dynamic and static basal friction on stick-slip and clogging dynamics
C. Manuel Carlevaro, Ryan Kozlowski, Luis A. Pugnaloni +3
We discuss the results of simulations of an intruder pulled through a two-dimensional granular system by a spring, using a model designed to lend insight into the experimental find…
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…
