Flow regimes and repose angle in a rotating drum filled with highly concave particles
Weiyi Wang, Jonathan Barés, Emilien Azéma
We present a series of experiments investigating the flow regimes and repose angles of highly concave particle packings in a rotating drum. By varying grain geometry from spherical…
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…
Compacting an assembly of soft balls far beyond the jammed state: insights from 3D imaging
Jonathan Barés, Manuel Cárdenas-Barrantes, Gustavo Pinzón +4
Very soft grain assemblies have unique shape-changing capabilities that allow them to be compressed far beyond the rigid jammed state by filling void spaces more effectively. Howev…
Stress-strain behavior and geometrical properties of packings of elongated particles
Émilien Azema, Farhang Radjaï
We present a numerical analysis of the effect of particle elongation on the quasistatic behavior of sheared granular media by means of the Contact Dynamics method. The particle sha…
