This paper attempts to establish a rational determination of the load-carrying capacity of an imperfect, cylindrical shell, subjected to a combined load. The investigated load is a combination of an axial compression force and an external hydrostatic pressure (where the end pressure on the cylinder is included). It is noted that theory does not imply any empiricism; it is based solely on a theoretical deduction. The knock-down factor accounts for the buckle imperfection and is estimated according to well-established classical theory. The influence of the oval imperfection and the yield stress is accounted for by a static analysis, in which the plate theory and the von Mise yield condition are used. The interaction curves are also derived from the static analysis and can be estimated by an impirical fourmla or by a simple formula. These and other findings are discussed.
