Design optimization is an effective tool to improve current designs by changing size, shape and topology by certain rules. In particular, one can find optimal designs even without any initial baseline layouts if the topology optimization method is employed. Thereby, truly-best solutions might be found with this method. Because topology can be optimized by this method, it can be used as a creative tool to find layout configurations or material distributions that exhibit the required function or performance. The method was originally developed for light-weight structure design, but it has been expanded to various non-structural problems. In this talk, some recent progress made in non-structural problems will be presented, including applications possibly related to material science and engineering.

 

For those who are not much exposed to the use of optimization methods, the underlying idea of optimization methods will be given first. This introduction includes some illustrations of successful industrial applications in cars and airplanes. We will present some interesting results obtained by the optimization method in problems dealing with rigid-link mechanisms, magnetoelectric multiferroic hetero-structures (figures shown below) and phononic crystals. The latter problems deal with optimal distributions of multi-materials.
