| Abstract: | The method of genetic algorithm is employed to solve the ply orientation angle optimization problem of composite laminates that have the unchanged total number of plies, to satisfy the requirements of natural frequencies of vibration. By means of optimization of a 20-ply symmetric laminate, it can be shown that this method can not only be used to solve the discrete problems successfully in the structural optimization, but also is possessed of higher computational efficiency.The method proposed in this paper is simple and can be adoped in more complicated structural optimization problems. |
