A METHOD FOR ELIMINATING THE EFFECT OF END CONDITIONS ON THE STRENGTH OF STIFFENED CYLINDRICAL SHELLS

Abstract

A pair of stiffened cylinders was subjected to external hydrostatic pressure to establish the adequacy of a design procedure for eliminating the effect of end conditions on strength. The cylinders were machined from a thick tube and were identical to those described in TMB Report 1326 except for the size and spacing of the frames and the thickness of the shell at the ends. The cylinders failed by axisymmetric shell yielding in the second full-length bay at identical collapse pressures. Test results indicated that, with these end conditions, the collapse pressure could be increased by 4 percent over that for a similar model in which the first bay length was two thirds of the length of the others, and failure could be shifted away from the ends of the cylinder.
