125Friction-Induced Instabilities and Vibrations
thickness between the two bodies. One surface is stationary and the other
undergoes a sliding motion at a constant speed. The system is operating
under a steady-state condition. To determine the susceptibility of this sys-
tem to TEI, a small surface wave, representing a disturbance, is imposed. The
imposed surface wave, even though it is very small, will affect the velocity
prole in the uid, the hydrodynamic pressure distribution, and the heat
balance within the lm. As a result, the entire deformation eld—both ther-
mal and mechanical—will be affected.
Jang and Khonsari (2003) studied whether at a given operating speed the
combination of these deformations grow unbounded, thus resulting in ...
