An approach to the construction of solutions to the plane problems of the theory of elasticity and thermoelasticity for nonhomogeneous multilayered solids, including modeling of nonhomogeneous solids with coatings, has been developed. Using the method of direct integration of equilibrium equations, the relationship between the components of the stress tensor is established. The equation of continuity in terms of stresses is reduced to the governing equation for the key stress components. In the same way, the boundary conditions for the corresponding components of the stress tensor are reduced to a system of boundary and integral conditions for the key stresses. With the application of the appropriate integral transformation, the obtained governing equations are reduced to Volterra integral equations, for the solution of which the resolvent method is used.
