A simple procedure uses the r-nodes to achieve minimum weight design of mechanical components and structures. The method is based on two linear elastic finite element analyses (or more) in order to arrive at a component configuration that would correspond to the minimum weight design. The proposed method is applied to pressure component configurations of practical interest.

Minimum weight analyses for unstiffened and ring-stiffened cylinders under external pressure are presented for designs based on stability and compressive yield-strength considerations. The results for both types of cylinders are compared in terms of a common set of parameters to establish the efficiency of the stiffening system. The results are then compared on a somewhat different basis to establish the relative efficiencies of various classes of materials. Finally, certain conclusions are drawn of particular pertinence to deep submersibles.
