The three-dimensional problem of the steady-state vibrations of isotropic sandwich plates with flat edges covered by diaphragms is solved. The layers are assumed perfectly bonded. Homogeneous solutions of the system of equations of motion for displacements are obtained. Asymptotic and numerical analyses of the dispersion equations are carried out. Spectral curves and curves of phase and group velocities are presented.
