| Abstract |
This paper provides the results on the shape and thickness optimization of shells. Five fundamental technologies such as computer-aided geometric design, automatic mesh generation, shell finite element, design sensitivity analysis and shell optimization process, are proposed for shell optimization maximizing the fundamental natural frequency and those are throughly described in this paper to give the essential information on the shell optimization for vibration problems. Various numerical examples are provided to prove the overall performance of shell optimization techniques proposed throughout this study. From numerical examples, the proposed shell optimization technique is found to be very efficient and can be effectively used for maximizing the fundamental frequency of shell structures with the limited construction material. |
