Analytical model for flux saturation in sediment transport
Thomas Pähtz, Eric J. R. Parteli, Jasper F. Kok +1
The transport of sediment by a fluid along the surface is responsible for dune formation, dust entrainment and for a rich diversity of patterns on the bottom of oceans, rivers, and…
Subdivision Shell Elements with Anisotropic Growth
Roman Vetter, Norbert Stoop, Thomas Jenni +2
A thin shell finite element approach based on Loop's subdivision surfaces is proposed, capable of dealing with large deformations and anisotropic growth. To this end, the Kirchhoff…
Generating Robust and Efficient Networks Under Targeted Attacks
Vitor H. P. Louzada, Fabio Daolio, Hans J. Herrmann +1
Much of our commerce and traveling depend on the efficient operation of large scale networks. Some of those, such as electric power grids, transportation systems, communication net…
Liquid migration in sheared unsaturated granular media
Roman Mani, Dirk Kadau, Hans J. Herrmann
We show how liquid migrates in sheared unsaturated granular media using a grain scale model for capillary bridges. Liquid is redistributed to neighboring contacts after rupture of…
Watersheds are Schramm-Loewner Evolution curves
E. Daryaei, N. A. M. Araujo, K. J. Schrenk +2
We show that in the continuum limit watersheds dividing drainage basins are Schramm-Loewner Evolution (SLE) curves, being described by one single parameter . Several numerical e…
Fluid depletion in shear bands
Roman Mani, Dirk Kadau, Dani Or +1
How does pore liquid reconfigure within shear bands in wet granular media? Conventional wisdom predicts that liquid is drawn into dilating granular media. We, however, find a deple…
