| Abstract: | Free vibration of a flexible plate floating on the free surface of a perfect incompressible finite-depth heavy liquid are studied. The problem is solved in the shallow water approximation. Conditions for the existence of discrete frequencies below the waveguide cutoff frequency and associated localized (nonpropagating) liquid vibration modes in the plate-liquid system are determined. |
