Nonlinear problems of the dynamics of elastic shells partially filled witha liquid

Theoretical and experimental investigations of the nonlinear vibrations and dynamic stability of thin shells partially filled with a liquid are review ed. The paper deals with the basic laws governing the dynamic high-deflecti on deformation of carrying shell structures and the considerable vibrations of the free liquid surface due to the natural, forced, and parametrically excited vibrations of the combined system and also due to impulse loads act ing on the carrying object. The nonlinear dynamic interaction of shells wit h a liquid filler is analyzed with allowance for the wave motions of the fr ee Liquid surface.
