Analytical Approach to Continuous and Intermittent Bottleneck Flows
Dirk Helbing, Anders Johansson, Joachim Mathiesen +2
We propose a many-particle-inspired theory for granular outflows from a hopper and for the escape dynamics through a bottleneck based on a continuity equation in polar coordinates.…
Flow in Rough Self-Affine Fractures Joints
José S. Andrade, Ascânio D. Araújo, Fernando A. Oliveira +1
We investigate viscous and non-viscous flow in two-dimensional self-affine fracture joints through direct numerical simulations of the Navier-Stokes equations. As a novel hydrodyna…
Gaussian Statistics of Fracture Surfaces
Stéphane Santucci, Joachim Mathiesen, Knut Jørgen Måløy +6
We analyse the statistical distribution function for the height fluctuations of brittle fracture surfaces using extensive experimental data sampled on widely different materials an…
Failure and avalanches in complex networks
Jan Øystein Haavig Bakke, Alex Hansen, János Kertész
We study the size distribution of power blackouts for the Norwegian and North American power grids. We find that for both systems the size distribution follows power laws with expo…
Rupture processes in fiber bundle models
Per C. Hemmer, Alex Hansen, Srutarshi Pradhan
Fiber bundles with statistically distributed thresholds for breakdown of individual fibers are interesting models of the static and dynamics of failures in materials under stress.…
