River-bed armoring as a granular segregation phenomenon
Behrooz Ferdowsi, Carlos P. Ortiz, Morgane Houssais +1
Gravel-river beds typically have an "armored" layer of coarse grains on the surface, which acts to protect finer particles underneath from erosion. River bed-load transport is a ki…
Acoustically-induced slip in sheared granular layers: application to dynamic earthquake triggering
Behrooz Ferdowsi, Michele Griffa, Robert A. Guyer +3
A fundamental mystery in earthquake physics is ``how can an earthquake be triggered by distant seismic sources?'' Here, we use discrete element method simulations of a granular lay…
Effect of boundary vibration on the frictional behavior of a dense sheared granular layer
B. Ferdowsi, M. Griffa, R. A. Guyer +2
We report results of 3D Discrete Element Method (DEM) simulations aiming at investigating the role of the boundary vibration in inducing frictional weakening in sheared granular la…
