Green's Function Measurements of Force Transmission in 2D Granular Materials
Junfei Geng, G. Reydellet, E. Clement +1
We describe experiments that probe the response to a point force of 2D granular systems under a variety of conditions. Using photoelastic particles to determine forces at the grain…

Footprints in Sand: The Response of a Granular Material to Local Perturbations
Junfei Geng, D. Howell, E. Longhi +5
We experimentally determine ensemble-averaged responses of granular packings to point forces, and we compare these results to recent models for force propagation in a granular mate…
