An Approach for the Reliability Based Design Optimization of Laminated Composite Plates

Résumé

This paper aims at optimizing laminated composite plates taking into account uncertainties in the structural dimensions. As laminated composites require a global optimization tool, the Particle Swarm (PSO) Optimization method was employed. A new reliability based design optimization (RBDO) methodology based on safety factors is presented and coupled with the PSO. Such safety factors are derived from the Karush-Kuhn-Tucker (KKT) optimality conditions of the reliability index approach and eliminate the need of the reliability analysis in the RBDO. The plate weight minimization was the objective function of the optimization process. The results showed the coupling of the evolutionary algorithm with the safety factor method proposed in this paper successfully performed the RBDO of laminated composite structures.
