INSTABILITY OF LONGITUDINALLY STIFFENED SHELLS.

Abstract

Buckling tests of longitudinally stiffened cylinders, fabricated with three stringer stiffnesses and four stringer spacings, are discussed. The panel buckling results are expressed in terms of a buckling coefficient and a geometric parameter. To determine analytically the cylinder buckling load, the longitudinal stiffeners are treated as a series of columns with lateral elastic supports furnished by the shell. Good correlation of the experimental results with semiempirical formulas was obtained. Within the ranges of the parameters investigated, designers may use these semiempirical formulas to predict the percent increase of buckling strength as a function of both stringer stiffness and stringer spacing.
