The Pressure-Viscosity Effect: Background

Indications are that the pressure-viscosity effect is an important factor in certain cases of lubrication, notably heavily-loaded elements. How important it is in the lubrication of lightly-loaded elements we do not know, nor do we know what refinements in design may be possible by taking this factor into account. The three papers which follow this introduction are modern contributions to our knowledge in this area. Following them, the Research Proposal on the Machine Element Test program will be discussed. Hopefully, the result of this presentation and discussion will be a better understanding of the importance of this problem and the potential value to industry of a solution to it.
