The stress-strain state at the interface between elastic media, which represents a contact layer characterized by the size and a set of physical-mechanical parameters, is investigated. The interface is described using the models of stratified and block media, within which the problem of a plane wave propagating through the interface is considered. The analytical expressions for the interface reflection and refraction coefficients are obtained, which allow determining the deformations at the interface and the strain distribution in the contact layer. The respective relationships for the dependence of deformation on the layer thickness at different elastic parameters of the contacting media and the interface are calculated. The regularities of deformation at the interface, described by the models of layered and block media, are analyzed. The areas of equivalent applications of these models are determined for the analysis of deformations at the interface and their distribution in the contact layer.
