•Hybrid plate-lattices exhibit higher energy absorption capacity and progressive failure compared to elementary ones.•The effectiveness of hybrid plate-lattices are more significant at higher impact energies (> 40 J).•The relative density decides the best balance between stiffness and unstable da...
