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…
