A direct link between active matter and sheared granular systems
Peter K. Morse, Sudeshna Roy, Elisabeth Agoritsas +3
The similarity in mechanical properties of dense active matter and sheared amorphous solids has been noted in recent years without a rigorous examination of the underlying mechanis…
Surface flow profiles for dry and wet granular materials by Particle Tracking Velocimetry; the effect of wall roughness
Sudeshna Roy, Bert J. Scheper, Harmen Polman +4
Two-dimensional Particle Tracking Velocimetry (PTV) is a promising technique to study the behaviour of granular flows. The aim is to experimentally determine the free surface width…
Towards a general(ized) shear thickening rheology of wet granular materials under small pressure
Sudeshna Roy, Stefan Luding, Thomas Weinhart
We study the rheology of dry and wet granular materials in the steady quasistatic regime using the Discrete Element Method (DEM) in a split-bottom ring shear cell with focus on the…
Micro-macro transition and simplified contact models for wet granular materials
Sudeshna Roy, Abhinendra Singh, Stefan Luding +1
Wet granular materials in a quasi-static steady state shear flow have been studied with discrete particle simulations. Macroscopic quantities, consistent with the conservation laws…
