Zusammenfassung:Within the framework of previously developed mathematical model of small elastic perturbations propagation in non-homogeneously strained elastic continuum a stationary problem for interaction of ultrasonic waves L - or Sv - polarization of normal falling with an elastic layer under plane deformation, which two elastic half-space is separated, has been formulated. The iterative procedure for its solution is built. With use the approximation of geometric optics the influence of non-uniform strains on the coefficients of reflected and refracted waves of different polarization has been studied.
