Аннотация:A contact between an infinitely extended plane indenter and a viscoelastic layer in the scope of a self-consistent approach according to Derjaguin under the surface application (traditional formulation) and bulk application (refined formulation) of intermolecular interaction forces is considered. Using the first law of thermodynamics, the problem of determining the energy dissipation in a viscoelastic layer is solved for a preset indenter approach/retraction law. Based on this solution, friction force under sliding a rough counterbody over a viscoelastic layer has been calculated. The results of the calculations indicate a significant effect of abrupt changing in the contact gap over time exerted on the energy dissipation and the friction force.
