The anisotropy of granular materials

F. Alonso-Marroquin, S. Luding, H. J. Herrmann

The effect of the anisotropy on the elastoplastic response of two dimensional packed samples of polygons is investigated here, using molecular dynamics simulation. We show a correl…

Rotationally driven gas of inelastic rough spheres

R. Cafiero, S. Luding, H. J. Herrmann

We study a two-dimensional gas of inelastic rough spheres, driven on the rotational degrees of freedom. Numerical simulations are compared to mean-field (MF) predictions with surpr…

Intermittent Granular Flow and Clogging with Internal Avalanches

S. S. Manna, H. J. Herrmann

The dynamics of intermittent granular flow through an orifice in a granular bin and the associated clogging due to formation of arches blocking the outlet, is studied numerically i…

Contact forces in regular 3D granular pile

G. Oron, H. J. Herrmann

We present exact results for the contact forces in a three dimensional static piling of identical, stiff and frictionless spheres. The pile studied is a pyramid of equilateral tria…

Exact calculation of force networks in granular piles

G. Oron, H. J. Herrmann

We present calculations of forces for two dimensional static sandpile models. Using a symbolic calculation software we obtain exact results for several different orientations of th…

Fluid Induced Particle Size Segregation in Sheared Granular Assemblies

Sitangshu Bikas Santra, Stefan Schwarzer, Hans Herrmann

We perform a two-dimensional molecular-dynamics study of a model for sheared bidisperse granular systems under conditions of simple shear and Poiseuille flow. We propose a mechanis…
