Abstract
The large-amplitude response of imperfect, simply supported circular cylindrical
shells to a harmonic excitation in the spectral neighbourhood of one of the lowest
natural frequencies is investigated. Donnell's nonlinear shallow-shell theory is
used and the solution is obtained by Galerkin projection. A multi-degree-of-
freedom mode expansion is used. The boundary conditions on radial
displacement and the continuity of circumferential displacement are exactly
satisfied. The effect of internal quiescent, incompressible and inviscid fluid is
investigated. The equations of motion are studied by using a code based on
arclength continuation method. Validation of the present model is obtained by
comparison with experimental results on a water-f
