Discrete numerical simulation, quasistatic deformation and the origins of strain in granular materials
Gaël Combe, Jean-Noël Roux
Systematic numerical simulations of model dense granular materials in monotonous, quasistatic deformation reveal the existence of two different régimes. In the first one, the macro…
Sound wave velocities in dry and lubricated granular packings packings: numerical simulations and experiments
Ivana Agnolin, Jean-Noël Roux, Pascal Massaad +2
Numerical simulations are used to investigate the origins of the different wave velocities measured in dense granular samples assembled with different methods. Glass bead packings…
Quasistatic rheology and the origins of strain
Jean-Noël Roux, Gaël Combe
Features of rheological laws applied to solid-like granular materials are recalled and confronted to microscopic approaches via discrete numerical simulations. We give examples of…
The nature of quasistatic deformation in granular materials
Jean-Noël Roux
Strain in granular materials in quasistatic conditions under varying stress originate in (I) contact deformation and (II) rearrangements of the contact network. Depending on sample…
Elasticity of sphere packings: pressure and initial state dependence
Ivana Agnolin, Jean-Noël Roux
Elastic properties and internal states of isotropic sphere packings are studied by numerical simulations. Several numerical protocols to assemble dense configurations are compared.…
Annular shear of cohesionless granular materials: from inertial to quasistatic regime
Georg Koval, Jean-Noël Roux, Alain Corfdir +1
Using discrete simulations, we investigate the behavior of a model granular material within an annular shear cell. Specifically, two-dimensional assemblies of disks are placed betw…
