8 - Vibration and collapse of novel pressure hulls

Abstract

The buckling and vibration of corrugated pressure vessels and tube-stiffened vessels and the collapse of inverted dome cups are discussed. Experimental results are compared with those from theoretical models using finite element analysis for cylinders in air and water. Dome cup ends were structurally more efficient than dome cap ends. A redesign of the corrugated food can is presented and shown to result in significant savings in manufacturing costs.
