Universality classes in creep rupture
Ferenc Kun, Yamir Moreno, Raul Cruz Hidalgo +1
We study the creep response of solids to a constant external load in the framework of a novel fiber bundle model introduced. Analytical and numerical calculations showed that incre…
Time evolution of damage under variable ranges of load transfer
Oluwole E. Yewande, Yamir Moreno, Ferenc Kun +2
We study the time evolution of damage in a fiber bundle model in which the range of interaction of fibers varies through an adjustable stress transfer function recently introduced.…
Scaling laws of creep rupture of fiber bundles
Ferenc Kun, Raul Cruz Hidalgo, Hans J. Herrmann +1
We study the creep rupture of fiber composites in the framework of fiber bundle models. Two novel fiber bundle models are introduced based on different microscopic mechanisms respo…
Evolution of percolating force chains in compressed granular media
Raul Cruz Hidalgo, Christian U. Grosse, Ferenc Kun +2
The evolution of effective force chains percolating through a compressed granular system is investigated. We performed experiments by compressing an ensemble of spherical particles…
Minimal model for aeolian sand dunes
Klaus Kroy, Gerd Sauermann, Hans J. Herrmann
We present a minimal model for the formation and migration of aeolian sand dunes. It combines a perturbative description of the turbulent wind velocity field above the dune with a…
Modelling a Dune Field
A. R. Lima, G. Sauermann, H. J. Herrmann +1
We present a model to describe the collective motion of barchan dunes in a field. Our model is able to reproduce the observation that a typical dune stays confined within a stripe.…
