| Abstract Scope |
Electric vehicles (EVs) introduce new challenges in vehicle architecture and load path management, particularly in ensuring crash protection for both passengers and battery packs. This study presents the development of stamped aluminum and steel structures featuring optimally designed patterns that offer high in-plane intrusion resistance. A multi-disciplinary CAE approach was employed to design and optimize dual-sheet patterned constructions that meet both springback requirements and intrusion performance targets. The simulated performance of these structures was validated through impact testing of prototype stamped aluminum panels. These innovative stamped designs offer a novel solution for creating nearly flat structural components, significantly reducing part complexity. By integrating complex formed patterns, the need for multiple reinforcement parts within the assembly is minimized, streamlining manufacturing and enhancing structural efficiency. |
