... appear in Figs. 5 and 6 , and that the location where bristle yield stress is reached (arrows) provides a basis for identifying the acceptable range of q o that can be sustained by the bristle. 2. Bristle/rotor contact force  2.1) The complementary load relations, in conjunction...

..., lubricant viscosity and pressure viscosity coefficient, material yield stress and sliding speed. Theoretical predictions for the change in pit area during the deformation process are well correlated by a non-dimensional group of these parameters. The model agrees reasonably with the measured change in pit...

... the thickness of the shear zone in lubricating films with fixed geometry between the stationary and moving surfaces using a Bingham model with a shear yield stress which best fits the experimental pressure. It is found that the shear zone thickness is significantly smaller than the fluid film thickness...
