In various practical structural design problems, decision of a layout of structure or stiffeners in the given design space satisfying some design requirements is the most difficult task for design engineers. Since they must consider many possible conditions for safety, performance and so on. It is also very difficult to solve the layout (topology) problem by any conventional structural optimization techniques because its mathematical modeling of topology is so complex. To solve the problem, we employed the new topology/layout optimization technique based on the homogenization method introduced by Bendsoe and Kikuchi. This method gives the minimum compliance design under a certain material constraint. In this paper we shall study a class of multi-loading problems for topology optimization by the homogenization method, and several car body design problems are solved to justify the validity and the strength of the present method for engineering applications.
