Computer simulation of fatigue under diametrical compression
H. A. Carmona, F. Kun, J. S. Andrade +1
We study the fatigue fracture of disordered materials by means of computer simulations of a discrete element model. We extend a two-dimensional fracture model to capture the micros…
Vegetation against dune mobility
Orencio Duran, Hans J. Herrmann
Vegetation is the most common and most reliable stabilizer of loose soil or sand. This ancient technique is for the first time cast into a set of equations of motion describing the…
Damage and Healing in Fatigue Fracture
F. Kun, M. H. A. S. Costa, R. N. Costa Filho +4
We present an experimental and theoretical study of the fatigue failure of asphalt under cyclic compression. Varying the load amplitude, experiments reveal a finite fatigue limit b…
Local load sharing fiber bundles with a lower cutoff of strength disorder
Frank Raischel, Ferenc Kun, Hans J. Herrmann
We study the failure properties of fiber bundles with a finite lower cutoff of the strength disorder varying the range of interaction between the limiting cases of completely globa…
A Stability Diagram for Dense Suspensions of Model Colloidal Al2O3-Particles in Shear Flow
Martin Hecht, Jens Harting, Hans J. Herrmann
In Al2O3 suspensions, depending on the experimental conditions very different microstructures can be found, comprising fluid like suspensions, a repulsive structure, and a clustere…
The Kauffman model on Small-World Topology
Carlos Handrey A. Ferraz, Hans J. Herrmann
We apply Kauffman's automata on small-world networks to study the crossover between the short-range and the infinite-range case. We perform accurate calculations on square lattices…
