Abstract

Composite materials are excellent candidates for structural optimization, as the best stacking sequence and fiber orientation varies with respect to loading condition. Typical aerospace applications experience multiple scenarios in flight, making it difficult to design a single “best” panel. While past research has explored individual cases – composite ply configuration, multiple load scenarios, and multiple performance objectives – there has been limited work addressing the interactions between these factors. This work builds upon previous efforts by constructing a Finite Element model and using multi-objective optimization techniques to explore the robustness of a composite across multiple load scenarios when considering a large number of angle orientations and competing objectives.
