ABSTRACT:
A circumferential rib-stiffened hollow cylinder and method for fabrication thereof featuring construction of the cylinder from complementarily shaped nestled prefabricated rings and resultant circumferential ribs which are integral with the rest of the cylinder. In one embodiment ring sections which are "L"-shaped in cross-section are axially and sequentially mated; ring sections which are "U"-shaped are axially and correspondingly integrated therewith, therein for a cylinder having internal circumferential ribs and thereout for a cylinder having external circumferential ribs. The dominant load path for the cylinder is through the reinforced cylinder elements, and the cylinder's wall-thickness-to-diameter ratio is effectively reduced, thereby allowing radial reinforcement of the ribs, reducing residual stresses and increasing strength; these advantages are especially significant for cylinders which are composite or are to be subjected to hydrostatic pressure. Moreover, in comparison with conventional cylinders of monocoque construction, manufacture and quality control may be expected to be more economical and cost-effective.
