Further Experimental Studies on Buckling of Ring Stiffened Conical Shells under Axial Compression

摘要

The buckling of integrally external ring stiffened conical shells under axial compression was investigated experimentally. Experimental results were compared with theory to find the effect of the stiffener parameters as well as of shell geometry. An approximate formula is proposed for calculation of critical loads and the influence of initial imperfections (out-of-roundness) of the shell on the critical load and growth of strains was studied.
