Paper online (Int J Mech Sci) on contact mechancis

Zhai, C., Hanaor, Gan, Y. (2017) Contact stiffness of multiscale surfaces by truncation analysis. International Journal of Mechanical Sciences. 131–132: 305–316. [DOI][PDF:048_IJMS_2017] Abstract: In this paper, we study the contact stiffness of a fractal rough surface compressed by a rigid flat plane. A numerical model based on the analysis of flat punch indentation is proposed for simulated hierarchical surfaces, […]

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

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 […]

Paper on arXiv: Normal contact stiffness

Chongpu Zhai, Sébastien Bevand, Yixiang Gan, Dorian Hanaor, Gwénaëlle Proust, Bruno Guelorget, Delphine Retraint (2014) Measurement of normal contact stiffness of fractal rough surfaces. We investigate the effects of roughness and fractality on the normal contact stiffness of rough surfaces. Samples of isotropically roughened aluminium surfaces are considered. The roughness and fractal dimension were altered […]
