Abstract

The article considers the solution of the problem of contact interaction of a cylindrical punch with an elastic layer taking into account the temperature at the free end of the punch. Thermal contact between the punch and the layer is not ideal and is carried out through a thin intermediate layer. The method of finding the temperature in the punch and layer and determining the contact stresses due to force and temperature field is constructed. Temperature and normal stresses are obtained as a series of Chebyshev functions, the coefficients of which are defined as the solution of a system of linear algebraic equations. Graphs of temperature and contact stresses in the layer are constructed.
