Some granular aspects of E.H.L. traction

Abstract A phenomenological examination of traction in elastohydrodynamic lubricated contacts shows there is a direct analogy with shear behaviour of beds of granules. The behaviour of a supposed granular lubricant under shear is formulated with regard to packing arrangements and agrees well with experimental results. The possibility of actual granularity in high-pressure lubricants is discussed and suggestions are made for methods of testing the hypothesis and for future work.
