Minimum film thickness in elliptical contacts for different regimes of fluid-film lubrication [PDF]
The film-parameter equations are provided for four fluid-film lubrication regimes found in elliptical contacts. These regimes are isoviscous-rigid; viscous-rigid; elastohydrodynamic of low-elastic-modulus materials, or isoviscous-elastic; and ...
