“…While there are several reports on plate vibrations with added point masses [3}6], very few reports on plate vibrations with distributed mass loading can be found in the literature. It has been proved that distributed mass loading can induce signi"cant changes of modal frequencies and shapes in beam vibrations [7,8]. In this paper, the free bending vibration of a simply supported rectangular plate carrying distributed mass loading is analyzed by the Rayleigh}Ritz method.…”
