Force fluctuation in a driven elastic chain
F. Lacombe, S. Zapperi, H. J. Herrmann
We study the dynamics of an elastic chain driven on a disordered substrate and analyze numerically the statistics of force fluctuations at the depinning transition. The probability…
Planar cracks in the fuse model
Stefano Zapperi, Hans J. Herrmann, Stephane Roux
We simulate the propagation of a planar crack in a quasi-two dimensional fuse model, confining the crack between two horizontal plates. We investigate the effect on the roughness o…
Macroscopic material properties from quasi-static, microscopic simulations of a two-dimensional shear-cell
Marc Lätzel, Stefan Luding, Hans J. Herrmann
One of the essential questions in the area of granular matter is, how to obtain macroscopic tensorial quantities like stress and strain from ``microscopic'' quantities like the con…
Models for Free Granular Surfaces
R. Mulet, H. Herrmann
We introduce two sets of continuum equations to describe granular flow on a free surface and study their properties. The equations derived from a microscopic picture that includes…
