The contact mechanics challenge: Problem definition
Martin H. Müser, Wolf B. Dapp
We present a contact mechanics problem, which we consider to be representative for contacts between nominally flat surfaces. The main ingredients of the mathematically fully define…
Fluid leakage near the percolation threshold
Wolf B. Dapp, Martin H. Müser
Percolation is a concept widely used in many fields of research and refers to the propagation of substances through porous media (e.g., coffee filtering), or the behaviour of compl…
Contact mechanics of and Reynolds flow through saddle points: On the coalescence of contact patches and the leakage rate through near-critical constrictions
Wolf B. Dapp, Martin H. Müser
We study numerically local models for the mechanical contact between two solids with rough surfaces. When the solids softly touch either through adhesion or by a small normal load…
Systematic analysis of Persson's contact mechanics theory of randomly rough elastic surfaces
Wolf B. Dapp, Nikolay Prodanov, Martin H. Müser
We systematically check explicit and implicit assumptions of Persson's contact mechanics theory. It casts the evolution of the pressure distribution with increasing r…
On the contact area and mean gap of rough, elastic contacts: Dimensional analysis, numerical corrections and reference data
Nikolay Prodanov, Wolf B. Dapp, Martin H. Müser
The description of elastic, nonadhesive contacts between solids with self-affine surface roughness seems to necessitate knowledge of a large number of parameters. However, few para…
Self-Affine Elastic Contacts: Percolation and Leakage
Wolf B. Dapp, Andreas Lücke, Bo N. J. Persson +1
We study fluid flow at the interfaces between elastic solids with randomly rough, self-affine surfaces. We show by numerical simulation that elastic deformation lowers the relative…
