“…However, the authors advised that further testing is needed to confirm the trends in this study, and to provide a measure of the likely scatter from a larger sample of experimental models (the reason is that in the absence of stiffening rings, buckling of the shell would occur at pressures only a fraction of that required to cause axisymmetric yield of the structure). In 2004, the buckling of three ring-stiffened prolate domes under external hydrostatic pressure was reported by Ross et al [154]. The effect of ring stiffening the domes was to increase their buckling resistance by factors varying from 4.43 to 5.72.…”

Stiffened panels made out of isotropic or anisotropic materials are being extensively used as structural elements for aircraft, maritime, and other structures. In order to maintain stiffness and strength with light weight, new design techniques must be employed when utilising these materials. Their stability, ultimate strength and loading capacity are the key issues pertaining to these engineering structures which have attracted a number of investigators to undertake in- depth research, either in an academic or actual engineering context. This paper provides an extensive review of the research which has been conducted in recent years (2000-2012) on the buckling and post-buckling response of isotropic and composite stiffened plate and shell structures related to analysis and experiment. The key objective of this review article is to collate the research performed in the area of buckling and post-buckling behaviour of stiffened structures, thereby giving a broad perspective of the state-of-the-art in this field.

“…Shells were made from magnesium or cast-epoxy. Ross [68][69][70][71][72][73][74][75][76] carried out a comprehensive experimental tests of the buckling behavior of ring stiffened thick mild steel cones under external pressure. He proposed a method for calculation of the theoretical elastic buckling pressure for a perfect cone, together with the thinness ratio.…”

The paper reviews literature on buckling of conical shells subjected to three loading conditions: (i) axial compression only, (ii) external pressure only and (iii) combined loading. The review is from the theoretical as well as experimental points of view. This review covers known experiments on cones from (1958 -2012). The literature review is split thematically into the following categories: theoretical prediction of axially compressed cones, theoretical prediction of externally pressurized cones, theoretical prediction of cones under combined loading, buckling experiments on axially compressed cones, buckling experiments on externally pressurized cones, buckling experiments on cones subjected to combined loading, buckling experiments on composite conical shells, equivalent cylinder approach, effect of initial geometric imperfection on the buckling behaviour of cones and effect of imperfect boundary conditions on the buckling behaviour of cones.

“…In this case, the ratio of p exp tl /p numerical varied between 0.62 and 0.80. In a separate research, with scattered results in Refs [88][89][90], a series of 15 mild steel cones reinforced by external rings have been tested under quasi-static external hydrostatic pressure. It is reported that the failures were sudden with a loud bang accompanying failure.…”

“…The previous research effort has primarily been limited to buckling by external hydrostatic pressure which in fact corresponds to combined loading due to axial compression resulting from pressure action on top/bottom flanges, e.g., Refs. [86,88,89,91].…”

This review aims to complement a milestone monograph by Singer et al. (2002, Buckling Experiments-Experimental Methods in Buckling of Thin-Walled Structures, Wiley, New York). Practical aspects of load bearing capacity are discussed under the general umbrella of "buckling." Plastic loads and burst pressures are included in addition to bifurcation and snap-through/collapse. The review concentrates on single and combined static stability of conical shells, cylinders, and their bowed out counterpart (axial compression and/or external pressure). Closed toroidal shells and domed ends onto pressure vessels subjected to internal and/or external pressures are also discussed. Domed ends include: torispheres, toricones, spherical caps, hemispheres, and ellipsoids. Most experiments have been carried in metals (mild steel, stainless steel, aluminum); however, details about hybrids (copper-steel-copper) and shells manufactured from carbon/glass fibers are included in the review. The existing concerns about geometric imperfections, uneven wall thickness, and influence of boundary conditions feature in reviewed research. They are supplemented by topics like imperfections in axial length of cylinders, imperfect load application, or erosion of the wall thickness. The latter topic tends to be more and more relevant due to ageing of vessels. While most experimentation has taken place on laboratory models, a small number of tests on full-scale models are also referenced.
