プライドロップ積層板の積層順序およびドロップオフ順序の同時最適化

抄録

This study proposes a simoultaneous design optimization for a ply drop-off laminated composite to maximize strength at the regin pocket in terms of both the stacking sequence and the ply drop-off placement under several empicical stacking constraints. Genetic algorithms including the gene repair strategy and adaptive mutation is adopted for efficient searching. The strength is evaluated based on the stress index based on FEM analysis using the three-layer model. Through numerical examples, the validity of the proposed simultaneous design method is demonstrated.
