Viscosity measurement in thin lubricant films using shear ultrasonic reflection [PDF]
, 2008 When a shear ultrasonic wave is incident on a solid and liquid boundary, the proportion that is reflected depends on the liquid viscosity. This is the basis for some instruments for on-line measurement of bulk liquid viscosity.

Operating limits for acoustic measurement of rolling bearing oil film thickness [PDF]
, 2003 An ultrasonic pulse striking a thin layer of liquid trapped between solid bodies will be partially reflected. The proportion reflected is a function of the layer stiffness, which in turn depends on the film thickness and its bulk modulus.

Measurement of interface pressure in interference fits [PDF]
, 2005 When components such as bearings or gears are pressed onto a shaft, the resulting interference induces a pressure at the interface. The size of this pressure is important as many components fail because fatigue initiates from press-fit stress ...
