Within the framework of Lorentz model for description of viscoelastic medium
the influence of deformational defect of the shear modulus is studied on
melting of ultrathin lubricant film confined between the atomically flat solid
surfaces. The possibility of jump-like and continuous melting is shown. Three
modes of lubricant behavior are found, which correspond to the zero shear
stress, the Hooke section of loading diagram, and the domain of plastic flow.
Transition between these modes can take place according to mechanisms of
first-order and second-order phase transformations.
Hysteresis of dependencies of
stationary stresses on strain and friction surfaces temperature is described.
Phase kinetics of the system is investigated. It is shown that ratio of the
relaxation times for the studied quantities influences qualitatively on the
character of the stationary mode setting.
