Abstract: The minimum weight design of the laminated composite plate with the number of plies and ply orientations considered as design variables is performed. Analyses of the characteristics of the optimization problem are carried out. Focusing on the characteristics of the optimization problem, an improved evolutionary algorithm is proposed. In the improved evolutionary algorithm, the search interval shrinks with the evolutionary process, and individuals in the population gather around the global optimal point gradually. Test examples show that the proposed algorithm has excellent global search ability.

Key words: laminated composite plate, the number of plies, ply orientation, optimization, differential evolu-
