TL;DR: In this article, the authors summarized the submissions to a recently announced contact-mechanics modeling challenge and provided both theorists and experimentalists with benchmarks to decide which method is the most appropriate for a particular application and to gauge the errors associated with each one.

TL;DR: Elastic deformation lowers the relative contact area at which contact patches percolate in comparison to traditional approaches to seals and suppresses leakage through contacts even far away from the percolation threshold.

TL;DR: In this paper, the authors derived the pressure dependence of the relative contact area and the mean interfacial separation between solids with self-affine surface roughness by combining dimensional analysis with numerical simulations and presented the results in a compact form.

TL;DR: In this paper, the relative contact area and the mean interfacial separation between solids with self-affine surface roughness were derived by combining dimensional analysis with numerical simulations. But the results in a compact form.

TL;DR: It is found that fortuitous error cancellations cannot be guaranteed under different circumstances, for instance when investigating rubber friction, and the results of the simulations may provide guidelines for a systematic improvement of the theory.
