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…
