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 --…
Loading-dependent microscale measures control bulk properties in granular material: an experimental test of the Stress-Force-Fabric relation
Carmen L. Lee, Ephraim Bililign, Emilien Azéma +1
The bulk behaviour of granular materials is tied to its mesoscale and particle-scale features: strength properties arise from the buildup of various anisotropic structures at the p…
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…
Particle scale anisotropy controls bulk properties in sheared granular materials
Carmen L. Lee, Ephraim Bililign, Emilien Azéma +1
The bulk dynamics of dense granular materials arise through a combination of particle-scale and mesoscale effects. Theoretical and numerical studies have shown that collective effe…
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…
