Effect of Eccentricity of Stiffeners on the General Instability of Stiffened Cylindrical Shells Under Torsion

Abstract

A method of analysis of eccentrically stiffened cylindrical shells, developed earlier, is applied to buckling under torsion. In the calculations about 350 shells covering a wide range of shell and stiffener geometries have been considered. It is found that for long cylinders rings are the important stiffeners, and internal rings stiffen more than external rings. For short cylinders the effect is inverted, external rings yielding higher critical loads than internal rings. Stringers have little effect in long cylinders, but in short cylinders they stiffen the shell against buckling in torsion as much as rings. Outside stringers always stiffen the shell more than inside stringers.
