A note on the upward and downward intruder segregation in granular media
L. Trujillo, H. J. Herrmann
The intruder segregation dependence on size and density is investigated in the framework of a hydrodynamic theoretical model for vibrated granular media. We propose a segregation m…
Analysis of the elasto-plastic response of a polygonal packing
F. Alonso-Marroquin, H. J. Herrmann, S. Luding
We investigate the constitutive response of two-dimensional packed samples of polygons using molecular dynamics simulation. The incremental elasto-plastic response is examined in t…
Size segregation and convection
Thorsten Poeschel, Hans J. Herrmann
The size segregation of granular materials in a vibrating container is investigated using Molecular Dynamics. We find that the rising of larger particles is accompanied by the exis…
Hydrodynamic model for particle size segregation in granular media
L. Trujillo, H. J. Herrmann
We present a hydrodynamic theoretical model for "Brazil nut" size segregation in granular materials. We give analytical solutions for the rise velocity of a large intruder particle…
