Statistical Properties of a 2D Granular Material Subjected to Cyclic Shear
J. Zhang, T. S. Majmudar, A. Tordesillas +1
This work focuses on the evolution of structure and stress for an experimental system of 2D photoelastic particles that is subjected to multiple cycles of pure shear. Throughout th…
Why Do Granular Materials Stiffen with Shear Rate? A Test of Novel Stress-Based Statistics
Robert P. Behringer, Dapeng Bi, Bulbul Chakraborty +2
Recent experiments exhibit a rate-dependence for granular shear such that the stress grows linearly in the logarithm of the shear rate, \dotγ. Assuming a generalized activated proc…
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…
Transients in sheared granular matter
Brian Utter, R. P. Behringer
As dense granular materials are sheared, a shear band and an anisotropic force network form. The approach to steady state behavior depends on the history of the packing and the exi…
Segregation by friction
L. Kondic, R. R. Hartley, S. G. K. Tennakoon +2
Granular materials are known to separate by size under a variety of circumstances. Experiments presented here and elucidated by modeling and MD simulation document a new segregatio…
