Viscoelastic effects in boundary lubrication

Abstract

THE traditional ‘time dependence of static friction’ approach, which is used to explain observed variations in static friction, has limited validity1. The appropriate governing variable is the rate of increase of the tangential force coefficient, θ̇, and not the static contact time as has been suggested previously1. (θ̇ = \[Fdot]/N where N is… (More)
