| Outline of Final Research Achievements |
In this project, we have studied various aspects of robustness evaluation as well as robust optimal design of structures. Particularly, by making use of the concept of duality which plays a significant role in optimization theory, we have developed a robust optimization method of structures possessing uncertainty in its configuration. It was difficult to deal with this sort of uncertainty by the existing methods. Also, besides problems in elasticity, we have developed methods dealing with uncertainty and robustness issues in various elastoplastic problems. Furthermore, as fundamentals for the robust design optimization methods developed in this project, we have presented a couple of new formulations for design optimization problems possessing combinatorial properties.
