Friction theories and wear mechanisms. Temperatures in sliding contacts. Hydrodynamic, hydrostatic, elastohydrodynamic and boundary lubrication. Surface failure due to rubbing is a critical problem ...

Professor Sakurai’s work on viscous oil films led to the concept of a critical contact pressure for operating limits of viscous films of base stocks, and to his discovery in elastohydrodynamic ...

This lubrication regime exists when the geometry, surface motion, and fluid viscosity create enough fluid pressure to cause hydrodynamic lift. Elastohydrodynamic lubrication regimes are formed when ...

This is given the name “elastohydrodynamic” lubrication because part of the picture is that curved tooth surfaces flatten ...

Inadequate lubrication, where the necessary hydrodynamic or elastohydrodynamic film is disrupted while the machine is under load, is a common cause of severe sliding wear. Factors contributing to ...
