RECENT EXPERIMENTAL STUDIES ON THE BUCKLING OF INTEGRALLY STRINGER-STIFFENED CYLINDRICAL SHELLS

Abstract

An experimental study of the buckling of closely spaced integrally stringer-stiffened cylindrical shells under axial compression was carried out to determine the influence of stiffener and shell geometry on the applicability of linear theory. 86 shells of different geometries were tested. Agreement between linear theory and experiments was found to be governed primarily by the stringer area parameter (A1/bh). Good correlation was obtained in the range (A1/bh) > 0.4. No significant effect of other stiffener and shell parameters on the applicability of linear theory could be discerned for the specimens tested. In addition to the area parameter (A1/bh), the inelastic behavior of the shell material was found to have a considerable effect on the 'linearity' (ratio of experimental buckling load to the predicted one).
