Origin of geometric cohesion in non-convex granular materials: interplay between interdigitation and rotational constraints enhancing frictional stability
Jonathan Barés, Arnaud Regazzi, David Aponte +4
We present a series of experiments investigating the local microstructure of cylindrical piles composed of highly concave particles. By systematically varying particle geometry --…
Experimental exploration of geometric cohesion and solid fraction in columns of highly non-convex Platonic polypods
David Aponte, Jonathan Barés, Mathieu Renouf +2
In this study, we investigate the stability and solid fraction of columns comprised of highly non-convex particles. These particles are constructed by extruding arms onto the faces…
Steady Granular Flow in a Rotating Drum: Universal description of stress, velocity and packing fraction profiles covering grain shape effects from convex to very concave
Weiyi Wang, Jonathan Barés, Mathieu Renouf +1
The flow behavior of granular matter is significantly influenced by the shape of constituent particles. This effect is particularly pronounced for very concave particles, which exh…
Relevance of visco-plastic theory in a multi-directional inhomogeneous granular flow
P. -P. Cortet, D. Bonamy, F. Daviaud +3
We confront a recent visco-plastic description of dense granular flows [P. Jop et al, Nature, {\bf 441} (2006) 727] with multi-directional inhomogeneous steady flows observed in no…
