ABSTRACT:
The design domain of an object to be designed is discretized by a plurality of nodes (10), and adjacent nodes and non-adjacent nodes are connected by beam elements (12). Optimization is performed on a design model constructed from the nodes (10) and beam elements (12), to obtain an initial design shape. When maximizing stiffness, the sensitivity of the stiffness matrix is determined, the cross sectional area of the beam elements with high sensitivity is increased, and the cross sectional area of the beam elements with low sensitivity is either reduced or set to zero so that low sensitivity beam elements are substantially removed. By constructing the design model using a plurality of beam elements, a reasonable shape satisfying the boundary condition can be obtained.
