Abstract

The chapter delves into the development of a new flange architecture for CFRP grid structures, utilizing additive manufacturing to reduce costs and simplify assembly. The design constraints and complex topology led to the selection of Electron Beam Melting (EBM) technology for titanium alloys. The study includes virtual testing in a non-linear static regime, incorporating material and contact non-linearities, and simulating both plasticization and failure of parts. Numerical results demonstrate the flanges' ability to withstand design loads while remaining in the linear elastic regime, with localized plasticization in small regions. The work also involves experimental validations and highlights the potential of the interconnection system in terms of structural efficiency and reduced mass compared to standard architectures.
