Shocks in non-loaded bead chains with impurities
E. Hascoet, H. Herrmann
We numerically investigate the problem of the propagation of a shock in an horizontal non-loaded granular chain with a bead interaction force exponent varying from unity to large v…
Cluster-Growth in Freely Cooling Granular Media
S. Luding, H. J. Herrmann
When dissipative particles are left alone, their fluctuation energy decays due to collisional interactions, clusters build up and grow with time until the system size is reached. W…
Dilatancy and Friction in sheared granular media
F. Lacombe, S. Zapperi, H. J. Herrmann
We introduce a simple model to describe the frictional properties of granular media under shear. We model the friction force in term of the horizontal velocity v and the vertical p…
Damage in Fiber Bundle Models
Ferenc Kun, Stefano Zapperi, Hans J. Herrmann
We introduce a continuous damage fiber bundle model that gives rise to macroscopic plasticity and compare its behavior with that of dry fiber bundles. Several interesting constitut…
Effect of impact energy on the shape of granular heaps
Yan Grasselli, Hans J. Herrmann, Gadi Oron +1
We study experimentally the shape of a granular heap formed pouring a granular material into a vertical Hele-Shaw cell and analyze the effect of the grain impact energy. We propose…
