“…During this series of tests, shells with different stiffener spacing, stiffener geometry and varying shell thickness with different taper ratio were investigated. Barkey et al [77] at Sandia National Laboratory studied the buckling behavior of thin-walled truncated cones made from ASTM 1008 steel. Cones were subjected to external pressure and formed a study into the structural integrity of a fusion related component.…”

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.

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.

“…Singer studied buckling behavior of the cones under axisymmetrically applied external pressure [5] and he also found the correlation of the conical shells with the equivalent cylindrical shells to predict the critical pressure [6]. Buckling of stiffened and unstiffened thin-walled truncated cones subjected to external pressure was studied and reported by Barkey et al [9]. The results of 19 specimens indicated that the buckling pressure values obtained from the tests were 60-80% of the FE and analytical calculations.…”
