This work demonstrates how architected and functionally graded lattice sandwich structures can significantly improve impact energy absorption while reducing peak loads. The results highlight a geometry-driven design strategy applicable to aeronautics, rotorcraft structures, and lightweight protective systems in transportation and defense industries.
