On lubricant transport conditions in elastohydrodynamic conjuctions

This is the authors' abstract. We don't add key points for this paper.

New numerical results, based upon the concept of solidification, are produced which match the intriguing dimple observed by Kaneta in elastohydrodynamic lubrication of point contacts under pure sliding conditions. It is shown that Kaneta's dimple is consistent with transport conditions of a solidified lubricant in the high-pressure region of the conjunction. The difference of velocity between the average velocity of the solidified core and the mean entraining velocity is referred to as 'slip'. The value of slip is shown to be related to the stress at the wall, which is deduced from the limiting shear stress.
