Original Abstract

This paper presents experimental results that point out on irregular distribution of through-film speed profile. The observations show an existence of cohesive core of entrainment speed surrounded by two shear zones located closely to the surfaces. This result represents experimental evidence for plug flow mechanism in highly loaded rolling-sliding elastohydrodynamic contact. Possible mechanisms of shear localization are discussed.
