It is reported that response of liquid-filled tank on a shaking table showed some vibration response that was contradiction to expectation of elementary tank vibration. Then, author has been studying to analyze the response that might be caused by dynamic geometric nonlinear behavior, and sowed a Lagrangian function that governed the interactive behavior between a potential fluid and elastic container in large deformations. Applying finite element methods to functional, a new formulation and a deriving a discretizing method are shown in the research. Numerical analyses of the nonlinear vibration response are carried out, the advantages of the procedure is demonstrated.
