Basing on the three-dimensional linearized equations of the elasticity theory of finite deformations for a solid and the three-dimensional linearized Euler equations for an ideal compressible fluid, the dispersion curves of quasi–Lamb normal waves in a hydroelastic system are constructed in a wide range of frequencies. The effects of initial stresses in the pre–deformed compressible elastic layer and the fluid layer thickness on the phase velocities of the quasi-Lamb modes in a hydroelastic waveguide are analyzed. The numerical results are presented in the form of graphs, and their analysis is given.
