Hui, David; Leissa, Arthur W. Effects of uni-directional geometric imperfections on vibrations of pressurized shallow spherical shells. (English) Zbl 0537.73049 Int. J. Non-Linear Mech. 18, 279-285 (1983). Summary: This paper deals with the effects of initial geometric uni-directional imperfections on vibrations of a pressurized shell or spherical cap. The analysis is based upon shallow shell theory. Frequency vs. applied pressure interaction curves are plotted for various values of the imperfection amplitude. Imperfections are shown to have a severe effect in reducing the natural frequencies similar to that demonstrated in the buckling behavior of spherical shells.
