【 摘 要 】

The article presents the solution of the axisymmetric problem of the stress-strain state of a two-layer hollow thick-walled cylinder. A model of limited length with loaded ends is considered. It is assumed that the interaction of layers is implemented through a contact layer. The contact layer is considered as a transversally anisotropic elastic medium with such parameters that it can be represented as a set of short elastic rods that are not connected to each other and are normally oriented to the contact surface. Such an assumption makes possible to obtain an analytical solution of the problem presented in a closed form. The solution obtained allows us to calculate essentially inhomogeneous stress and strain fields, including stress concentrations, and also satisfies all boundary conditions.
