Simultaneous optimization of composite shells, metallic components and their joints

Year: 2025

Type: article

Abstract: This paper presents an approach for the simultaneous topology optimization of an isotropic (for instance metallic) part, the layup optimization of a composite part, and the search for the optimized position of joints between the parts. Within a gradient-based optimization, a failure criterion for the composite acts as a constraint. The constraint’s gradients with respect to fiber orientations, pseudo densities of the isotropic elements, and joint positions are presented. As an example, the load introduction into an isotropic component that is attached to a composite plate is shown. The results show a significant influence of the considered constraint on the optimized overall design.
