The asymptotic solutions of heat problem of friction for a three-element tribosystem with generalized boundary conditions on the surface of sliding

The asymptotic (at large and small values of the dimensionless time) solutions are obtained to the heat problem of friction for the three-element tribosystem – the semi-space/the strip/the semi-infinity foundation. Comparison of values of the temperature obtained by means of exact (in the quadratures or the functional series) and asymptotic solutions at different values of the input parameters is executed. This allows to establish of the time limits their applications.
