“…Engineering methods for solving contact problems on the basis of simplifying hypotheses, for example, the representation of a layered body as a topocomposite-constructions with special mechanical properties, depending on the mechanical properties of the base and coating materials, the thickness of the coating, should be included in a separate group. In [9,10], it was proposed to use the Hertz theory for this purpose. On the basis of reliable results for the extreme thickness values of the coating, an expression is obtained for the dimensionless elastic geometric parameter Φ connecting the displacement of the surface of the topocomposite with the displacement of the surface of a homogeneous half-space from the base material.…”

A layered half-space is represented as the sum of parts of homogeneous half-spaces of coating materials and the base material, the rigidity of which corresponds to the rigidities of the coating and the base. Using a rigid model of a layered elastic body loaded with an axisymmetric distributed load, a new solution is obtained for determining its reduced elasticity modulus and the Poisson’s ratio depending on the elastic characteristics of the base material, the coating material and the relative thickness of the coating. Expressions are given for the reduced elastic modulus and the Poisson’s ratio of a layered body with a two-layer coating.
