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…
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…
Sliding Friction of Hard Sliders on Rubber: Theory and Experiment
R. Xu, B. N. J. Persson
We present a study of sliding friction for rigid triangular steel sliders on soft rubber substrates under both lubricated and dry conditions. For rubber surfaces lubricated with a…
Rubber Wear: History, Mechanisms, and Perspectives
R. Xu, W. Sheng, F. Zhou +1
This paper presents a comprehensive review of wear mechanisms, with a primary focus on rubber wear under sliding conditions. Beginning with classical wear theories, including the A…
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…
On how to determine surface roughness power spectra
N. Rodriguez, L. Gontard, C. Ma +2
Analytical contact mechanics theories depend on surface roughness through the surface roughness power spectrum. In the present study, we evaluated the usability of various experime…
