Extended Structural Synthesis Capability for Automated Design of Frame-Stiffened, Submersible, Circular, Cylindrical Shells,
Abstract
The report presents a procedure and computer program for the minimum weight design of circular, cylindrical, 'T' frame (ring) reinforced, submersible shells where all metal thicknesses may be confined to specified gage thickness values. Using the designer specified parameters defining shell radius, shell length, eccentricity, operating depth, design factors of safety, construction materials properties, and, when used, the specified gage thickness values, the program will generate those values of skin thickness, stiffener web and flange thicknesses, stiffener web depth and flange width, and if desired, stiffner spacing that will produce the smallest shell weight to liquid weight displaced ratio. Design equations control general, shell (skin) and stiffener instability, and skin and stiffener yielding. (Modified author abstract)
