The present work addresses topology optimization applied to thin-walled structures modeled with MITC4 shell finite elements under geometrically nonlinear behavior. The problem is formulated as the minimization of the structural end compliance subject to a volume constraint, with the aim of obtaining lightweight designs without compromising the mechanical response. The developed numerical tool was validated against benchmark results available in the literature for both in-plane and outof- plane responses, demonstrating the versatility and robustness of the adopted formulation. Finally, an industrially relevant application is presented on a B-pillar panel of an automotive chassis, where optimized lightweight components were obtained under different admissible solid material fractions, while maintaining compliance with the required service conditions.
