000014359 520__ $$2eng$$aLaminated composite structures are typically thin-walled structures that are prone to buckling, when compressed. To fully utilize the capabilities of such structures, the post-buckling response should be considered and optimized in the design process. This work presents a novel method for gradient based design optimization of the post-buckling performance of such structures. The post-buckling analysis is based on Koiter’s asymptotic method. The design sensitivities of the Koiter factors are derived using the direct differentiation method and new design optimization formulations based on the Koiter factors are presented. The proposed optimization formulations are demonstrated on a square laminated composite plate and a curved panel where the post-buckling stability is optimized.
