Transient fluid removal at soft interfaces: Contact-time-controlled squeeze-out in a cylinder-on-flat contact
R. Xu, B. N. J. Persson
We study transient fluid removal in cylinder-on-flat contacts between stiff PMMA cylinders and a soft PDMS substrate. The cylinder geometry eliminates the edge-scraping mechanism t…
Transient fluid removal at soft interfaces: Stationary squeeze-out and dynamic scraping in a block-on-flat contact
R. Xu, T. Tada, D. Ferré Sentis +1
Fluid removal from rubber-substrate interfaces is crucial for maintaining friction during walking and vehicle braking on contaminated surfaces. We study the transient friction of r…
Role of transfer films and interfacial cracking in metallic sliding wear
R. Xu, B. N. J. Persson
The origin of wear particles in metallic sliding contacts remains debated. Classical views based on cold-welded junctions suggest that plastic yielding of the real contact area sho…
Leakage at interfaces: a comprehensive study based on Persson contact mechanics theory
R. Xu, L. Gil, J. Singer +3
We present a comprehensive study of gas leakage at interfaces based on Persson contact mechanics theory. A prototype syringe system consisting of a rubber stopper and a glass barre…
Rubber Friction: Theory, Mechanisms, and Challenges
B. N. J. Persson, R. Xu
Rubber friction is of major practical importance in applications such as tires, rubber seals, and footwear. This review article focuses on the theory and experimental studies of ru…
Rubber wear on concrete: dry and in-water conditions
R. Xu, N. Miyashita, B. N. J. Persson
Rubber wear results from the removal of small (micrometer-sized) rubber particles through crack propagation. In this study, we investigate the wear behavior of Styrene-Butadiene Ru…
Rubber wear: experiment and theory
B. N. J. Persson, R. Xu, N. Miyashita
We study the wear rate (mass loss per unit sliding distance) of a tire tread rubber compound sliding on concrete paver surfaces under dry and wet conditions, at different nominal c…
