Buckling of Circular Cylindrical Shells with Evenly Spaced, Equal Strength Circular Ring Frames. Part Ii

Résumé du livre

A strain-energy solution of the buckling of a circular cylindrical shell reinforced by evenly spaced circular ring frames of equal strength under hydrostatic pressure was obtained in Part I. The buckled shape was assumed to be sinusoidal with inflection points at the location of the ring frames. For several geometrical configurations the critical pressure was found to be from two to three times that given by the von Mises solution. The assumed buckled shape used in Report I was modified to permit the inflection points of the deformed shape to occur between ring frames. For the geometrical configurations calculated in Report I, the critical pressure was found to be about one and one-third times that given by the von Mises solution. This represents a marked improvement over the solution obtained in Report I. (Author).
