Abstract
The problem of steady-state vibrations of elastic space contaning elastic infinite strip under the action of a linear source of harmonic vibrations is considered. The problem is solved with the aid of Fourier integral transformation. It is shown that in some cases of elastic parameters' values of the strip and the space, surface waves appear, which are localized on the contact surface of the elastic strip and the space. The displacement amplitude of the elastic strip and the space are represented in the form of a sum of the above mentioned surface waves and shear volume waves. Asymptotic expressions in far field are derived for the displacements of the elastic strip in the case of different values of parametrs, from which it can be seen that the shear volume wave in the strip has the same propagation speed as the shear volume wave of the space. Asymptotic expressions in far field for the displacements of the elastic space are also derived. The case of a thin elastic strip is also considered in the paper.
