The evolution of fractal surface structures with flattening of asperities was investigated using isotropically roughened aluminium surfaces loaded in compression. It was found that asperity amplitude, mean roughness and fractal dimension decrease through increased compressive stress and number of loading events. Of the samples tested, surfaces subjected to an increased number of loading events exhibited the most significant surface deformation and were observed to exhibit higher levels of…

Static friction at fractal interfaces
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

Static friction between rigid fractal surfaces.
Using spheropolygon-based simulations and contact slope analysis, the effects of surface topography and atomic scale friction on the macroscopically observed friction between rigid blocks with fractal surface structures are investigated and the description of frictional properties of Weierstrass-Mandelbrot surfaces is applied.

Effect of cyclic shearing on contact surfaces of geo-materials under constant normal force
A large amount of research has been done on conforming surfaces in rock joints as well as on the contact between individual grains; however, not much exist in nonconforming contact surfaces subjected

Rough surfaces are characterized by fractal geometry using a modified two-variable Weierstrass–Mandelbrot function. The developed algorithm yields three-dimensional fractal surface topographies

It is demonstrated that soft solid interfaces can be appreciably strengthened by reducing both fractal dimension and surface roughness, indicating a general route for tailoring the mechanical properties of solid bodies.

Abstract The elastic–plastic adhesive contact of rough surfaces is extended to include asymmetric distribution of asperity heights using the Weibull distribution with skewness as the key parameter to

Nanometre-scale roughness on a solid surface has significant effects on friction, since intersurface forces operate predominantly within a nanometre-scale gap distance in frictional contact. To study

Adhesion-dependent negative friction coefficient on chemically modified graphite at the nanoscale.
It is shown that, when adhesion between the AFM tip and surface is enhanced relative to the exfoliation energy of graphite, friction can increase as the load decreases under tip retraction, leading to the emergence of an effectively negative coefficient of friction in the low-load regime.

It is usually assumed that the real area of contact between two nominally flat metal surfaces is determined by the plastic deformation of their highest asperities. This leads at once to the result
