Analysis of the deformed state in elastic bodies AT THE interface under the conditions of ideal contact and sliping

In the work the deformed state at the interface in contacting bodies under conditions of ideal contact and sliping of the bodies. The considered boundary conditions are implemented at the interfaces of multiphase and structurally inhomogeneous elastic bodies in the processes of friction, propagation of surface waves and are used in solving many problems. The study of the deformed state at the interface of elastic bodies is carried out in the framework of the problem of the elastic wave propagation through the interface. The obtained analytical expressions for the Fresnel coefficients make it possible to calculate their dependences and the dependences of the strain amplitudes in the contacting bodies on the incidence angle of wave on the interface under conditions of perfect contact and slip. The influence of boundary conditions, the properties of the contacting bodies and the character of external action, determined by the type of the incident wave, on the deformed state at the boundary is analyzed.
