A Study on Robust Optimal Design of Laminated Composite Structures with Buckling Constraints

좌굴을 고려한 적층 복합재 구조의 강건 최적설계에 관한 연구

  • Published : 2001.09.01


A robust optimization procedure is applied to determine the design of the laminated composite plates with buckling constraints. In order to investigate the variation effect to the whole performance of a structure, both design variables and system parameters are assumed as random variables about their nominal values. The robust optimization method has advantages that the mean value and the variation of the performance function are controlled simultaneously and the second order sensitivity information is not required. Considering the information of uncertainty, robust optima for the buckling load of the laminated composite plates with cut-out is obtained. The robustness of the structures is compared to that of the deterministic optimization using scaling factors.
