Description

The eccentricity effect of stiffeners is studied for stiffened cylindrical shells under axial compression,. Classical simple supports and classical clamped ends are considered. A detailed physical explanation of the causes of the eccentricity effect and its behavior is proposed and verified by computations for 350 typical shells, As for buckling under hydrostatic pressure and torsion studied earlier, the behavior of the eccentricity
effect in the case of axial compression also depends very strongly on the geometry of the shell, represented by the Batdorf parameter, while the geometry of the stiffeners only influences its magnitude. Inversion of eccentricity effect occurs at very low Z , but for practical dimensions outside stringers always stiffen the shell more than insipe ones. The eccentricity effect has a pronounced maximum at practical values of Z , and the behavior of the eccentricity· effect is very similar for clamped and simply supported shells. Rings, which are much less effective stiffeners than stringers under axial compression, are also considered. Results are compared with those. of other investigators.
