Paper online on Static friction at fractal interfaces (Tribology International)

By drgan | Published: 21/09/2015

Dorian Hanaor, Yixiang Gan, and Itai Einav. “Static friction at fractal interfaces.” Tribology International (in press). DOI:?http://dx.doi.org/10.1016/j.triboint.2015.09.016 Abstract:?Tribological phenomena are governed by combined effects of material properties, topology and surface-chemistry. We study the interplay of multiscale surface structures with molecular-scale interactions towards interpreting static frictional interactions at fractal interfaces. By spline-assisted-discretization we analyse asperity interactions […]
