This paper reports a series of experimental studies on the vibration characteristics of circular cylindrical shells containing water under axial excitation. The conditions for the formation of bubble clusters in the fluid during the vibration and the interaction between the shell and the fluid are investigated. The pressure distributions and strains in the tank are correlated. Dynamic responses of the pressure and strains after bubble formation are observed. The wave velocity of the liquid-container system is also determined. It was found that the pressure equation derived, based on one-dimensional strain, could be made to agree with the experimental result when the wave velocity was corrected by an experimentally determined factor. The deformation of the tank was not axisymmetrical in most cases during the vibration. The inertia effect of the tank was not quite negligible. Drastic changes in the pressure and strain were observed after bubble formation.
