AB  - The load support by lubricants trapped in a dent was investigated using combined experimental and modeling study. The plastic deformation of the pre-indent shoulders for the dry case was greater than for the lubricated case, indicating that the entrapped lubricant was supporting a significant proportion of the applied load. By varying the pre-indent geometry, the load support depended on the conformity of the contacting surfaces, the relative change in volume, and thus the pressure increase of the trapped lubricant. For a conforming geometry, and assuming no leakage of oil from the pre-indent, the entrapped lubricant can support 60% of the applied load, assuming 50% leakage, the entrapped lubricant supported 34% of the applied load. By ignoring the effect of lubricants trapped in dents, the fatigue life of rolling element bearings could be underestimated. This is an abstract of a paper presented at the World Tribology Congress (Kyoto, Japan 9/6-11/209).
