| Abstract: |
| A stacking sequence optimization design approach of composite stiffened panel was built up based on equivalent bending stiffness method and Genetic Algorithms (GA). Very well known the fact that one laminate bending stiffness is corresponding to one buckling load, an arbitrary stacking sequence laminate to be equivalent auxiliary laminate only eight plies in the presented method. Firstly, optimal bending lamination parameters are obtained by optimizing auxiliary laminate. Then the stacking sequence solution is obtained with genetic algorithms for the optimal bending lamination parameters. One composite stiffened panel was optimized with the proposed method as example, and the optimization result demonstrated that the stacking sequence optimization of composite stiffened panel can be accomplished effectively based on equivalent bending stiffness. |
