Abstract: The effect of film thickness in solid friction is reviewed. Two regimes are distinguished: (a) increasing coefficient of friction with decreasing film thickness which occurs for ultrathin films ...

Abstract: A new approach to the analysis of problems of surface contact is postulated, which takes into account the discrete nature of the process, but allows the simplicity of continuum methods, where ...

Abstract: A review of the literature establishes that the wear of bonded solid lubricant films for conditions of low average contact stress (say 10,000 psi and below), obeys an equation of the form V ...

Abstract: Recent advances in applied mechanics are utilized to show that Rabinowicz’s experimental results for the friction of lead films as a function of film thickness can be related to the dependence ...

Abstract: Various abrasive wear resistance criteria are reviewed. These include hardness, modulus of elasticity, elastic strain limit, elastic-to-plastic contact transition factor, and elastic strain energy ...

Abstract: A mathematical analysis is offered showing the various consequences of spline friction in multiple disk systems. Included are equations for the load variation through a multiple disk pack, the ...
