Morphology-resolved stress contributions in sheared wet granular materials
Ahmad Awdi, Camille Chateau, Coumba Niang +3
Three-dimensional X-ray microtomography, coupled to rheometric measurements, enables a morphology-resolved reconstruction of capillary stresses at the grain scale in unsaturated we…
Computer simulation of model cohesive powders: Plastic consolidation, structural changes and elasticity under isotropic loads
Francisco Gilabert, Jean-Noël Roux, Antonio Castellanos
The quasistatic behavior of a simple 2D model of a cohesive powder under isotropic loads is investigated by Discrete Element simulations. The loose packing states, as studied in a…
On the elastic moduli of three-dimensional assemblies of spheres: characterization and modeling of fluctuations in the particle displacement and rotation
I. Agnolin, J. -N. Roux
The elastic moduli of four numerical random isotropic packings of Hertzian spheres are studied. The four samples are assembled with different preparation procedures, two of which a…
Strain versus stress in a model granular material: a Devil's staircase
Gael Combe, Jean-Noel Roux
The series of equilibrium states reached by disordered packings of rigid, frictionless discs in two dimensions, under gradually varying stress, are studied by numerical simulations…
Geometric origin of mechanical properties of granular materials
Jean-Noel Roux
Some remarkable generic properties, related to isostaticity and potential energy minimization, of equilibrium configurations of assemblies of rigid, frictionless grains are studied…
