Abstract

In order to fully exploit the benefits provided by using composite materials in large scale aerospace structures, more efficient detailed design optimisation techniques need to be developed. In the present work, the optimisation procedure is split up in one gradient-based step that yields an optimal thickness and stiffness distribution which is then matched by a following discrete optimisation step. The output structure meets prescribed design and manufacturing rules commonly applied in composite design, through the implementation of a novel Mixed Integer Linear Programming formulation of the problem. The results indicate the need for more efficient discretisation techniques .
