Abstract

The paper reports on a theoretical and an experimental investigation into the vibration and buckling of an hemi-ellipsoidal tube-stiffened dome under external water pressure. The theoretical analyses were via the finite element method. where both the fluid and the structure were modelled with finite elements. The dome was modelled with a varying meridional curvature element and with eight displacement degrees of freedom and the water was modelled by solid annular elements where each element had eight pressure degrees of freedom. Comparison was good between experiment and theory.
