Popis:	This paper is dedicated to the solution of a coupled problem on creep and viscoplastic flow in a flat heavy layer. The layer is on an inclined surface and subject to heating and cooling. The problem has been solved in the framework of the large elastoplastic strain mathematical model, which generalized for the case of taking into account rheological and thermophysical material properties. The thermophysical and deformation processes are interconnected; a yield limit, a viscosity factor and creep parameters depend on temperature. The patterns of the motion of elastoplastic boundaries are shown, stresses, strains and strain rates in the areas of flow and thermoviscoelastic deformation has been calculated.
