WebMar 1, 1994 · This paper focuses on the buckling of cylindrical shells with small thickness variations. Two important cases of thickness variation pattern are considered. Asymptotic formulas up to the second order of the thickness variation parameter ε are derived by the combination of the perturbation and weighted residual methods. The expressions … WebAug 1, 1996 · A theoretical investigation of the buckling of cylindrical shells under uniform external lateral pressure loading is presented, based on Flügge's stability equations in …
WebThe efficient method of significantly increasing the buckling resistance is by stiffening the thin cylindrical shell at their flanges with ring stiffeners. If the ring stiffeners becomes weak, the ring-shell combination can collapse under external loading and the mode of failure is known as general instability failure mode as shown in Fig. 1. The ratio of the effective length of a column to the least radius of gyration of its cross section is called the slenderness ratio (sometimes expressed with the Greek letter lambda, λ). This ratio affords a means of classifying columns and their failure mode. The slenderness ratio is important for design considerations. All the following are approximate values used for convenience.
