Abstract
Within the framework of previously developed mathematical model of small elastic perturbations propagation in homogeneously strained elastic continuum a stationary problem for interaction of a narrow ultrasonic beam of SH polarization waves with an elastic layer under plane deformation has been formulated. In the problem the phenomenon of interference of reflected and refracted waves on surface of including small elastic perturbations in strained solid has been taken into account. The problem was solved by the iterative method. With use the approximation of geometric optics the parameters of reflected and refracted waves in the system «elastic half-space – the layer – elastic half-space» has been obtained. The influence of plane strain parameters on the coefficients of reflected and refracted waves has been studied.
