This paper deals with a method of generating a multiple connected region and shape optimization for reducing the weight and stress concentration of mechanical structural components. Structural components often contain some holes for the purpose of reducing their weight. It is a difficult task to determine the optimum number, position and shape of holes under various constraints in the conceptual phase of design. In this study, we propose a method of shape generation for obtaining minimum weight and maximum stiffness for clastic structural components using a genetic algorithm. We describe in detail how to apply the genetic algorithm to determine the multiple connected region and its optimization. We show some results of typical problems to demonstrate the effectiveness of the proposed method.
