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…
Experiments in randomly agitated granular assemblies close to the jamming transition
G. Caballero, A. Lindner, G. Ovarlez +3
We present here the preliminary results obtained for two experiments on randomly agitated granular assemblies using a novel way of shaking. First we discuss the transport propertie…
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…
Green's function probe of a static granular piling
Guillaume Reydellet, Eric Clément
We present an experiment which aim is to investigate the mechanical properties of a static granular assembly. The piling is an horizontal 3D granular layer confined in a box, we ap…
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…
