Abstract
Based on three-dimensional equations of linearized elasticity theory for finite deformations of elastic body and three-dimensional linearized Navier-Stokes equations for the liquid medium, the problem of propagation of acoustic waves in preliminarily deformed compressible elastic layer in contact with a layer of viscous compressible liquid has been formulated. A numerical study is conducted, dispersion curves are constructed and dependencies of the phase velocities and attenuation coefficients modes to the thickness of layers of elastic body and a viscous compressible liquid in a wide frequency range are determined. An effect of initial stresses on phase-frequency spectrum of waves in the hydroelastic system is analyzed.
