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…
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.…
On the elastic moduli of two-dimensional assemblies of disks: relevance and modeling of fluctuations in particle displacements and rotations
I. Agnolin, N. P. Kruyt
We determine the elastic moduli of two-dimensional assemblies of disks by computer simulations. The disks interact through elastic contact forces, that oppose the relative displace…
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…
Internal states of model isotropic granular packings. III. Elastic properties
Ivana Agnolin, Jean-Noël Roux
In this third and final paper of a series, elastic properties of numerically simulated isotropic packings of spherical beads assembled by different procedures and subjected to a va…
Internal states of model isotropic granular packings. II. Compression and pressure cycles
Ivana Agnolin, Jean-Noël Roux
This is the second paper of a series of three investigating, by numerical means, the geometric and mechanical properties of spherical bead packings under isotropic stresses. We stu…
