From the stress response function (back) to the sandpile `dip'
A. P. F. Atman, P. Brunet, J. Geng +4
We relate the pressure `dip' observed at the bottom of a sandpile prepared by successive avalanches to the stress profile obtained on sheared granular layers in response to a local…

Sensitivity of the stress response function to packing preparation
A. P. F. Atman, P. Brunet, J. Geng +5
A granular assembly composed of a collection of identical grains may pack under different microscopic configurations with microscopic features that are sensitive to the preparation…

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…
