Earthquake dynamics constrained from laboratory experiments: new insights from granular materials
Andrea Bizzarri, Alberto Petri, Andrea Baldassarri
The traction evolution is a fundamental ingredient to model the dynamics of an earthquake rupture which ultimately controls, during the coseismic phase, the energy release, the str…
Shear profile in a dense packing of large grains
Alessio Quaresima, Andrea Plati, Andrea Gnoli +1
We investigate the shear of a dense bed of refracting supermillimetric grains confined within a transparent horizontal annular cell with a rotating top. The local time correlation…
Rescaling invariance and anomalous energy transport in a small vertical column of grains
Andrea Gnoli, Giorgio Pontuale, Andrea Puglisi +1
It is well known that energy dissipation and finite size can deeply affect the dynamics of granular matter, often making usual hydrodynamic approaches problematic. Here we report o…
Random neighbour model for yielding
Fergal Dalton, Alberto Petri, Giorgio Pontuale
We introduce a model for yielding, inspired by fracture models and the failure of a sheared granular medium in which the applied shear is resisted by self-organized force chains. T…
Brownian motor in a granular medium
Riccardo Balzan, Fergal Dalton, Vittorio Loreto +2
In this work we experimentally study the behavior of a freely-rotating asymmetric probe immersed in a vibrated granular medium. For a wide variety of vibration conditions the probe…
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…
