Brief description:

This research aims to investigate the crashworthiness performance of hybrid 3D-printed metamaterial resin structures reinforced with composite materials for railway applications. A multi-scale approach is adopted, integrating finite element modeling (FEM) to capture nonlinear deformation, progressive failure, and energy absorption mechanisms under impact loading. The numerical predictions are systematically validated through controlled experimental testing, ensuring the reliability of the constitutive models and failure criteria. Furthermore, a design optimization framework is implemented to tailor the metamaterial architecture and composite reinforcement, targeting enhanced specific energy absorption, load bearing efficiency, and structural stability under crash conditions.
