Stochastic dynamics of a sheared granular medium
Alberto Petri, Andrea Baldassarri, Fergal Dalton +3
We experimentally investigate the response of a sheared granular medium in a Couette geometry. The apparatus exhibits the expected stick-slip motion and we probe it in the very int…
Shear stress fluctuations in the granular liquid and solid phases
Fergal Dalton, Francis Farrelly, Alberto Petri +3
We report on experimentally observed shear stress fluctuations in both granular solid and fluid states, showing that they are non-Gaussian at low shear rates, reflecting the predom…
Brownian forces in sheared granular matter
Andrea Baldassarri, Fergal Dalton, Alberto Petri +3
We present results from a series of experiments on a granular medium sheared in a Couette geometry and show that their statistical properties can be computed in a quantitative way…
