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.
