Abstract: A novel honeycomb was proposed by adding double arrowhead cells into star-shaped honeycomb (SSH), and named as star-arrowhead honeycomb (SAH). The dynamic crushing behaviors and energy absorption capacities of the evolved structure SAH were systematically studied by finite element method with the commercial software package ANSYS/LS-DYNA explicit code. Adding double arrowhead cells into SSH improves the localized necking deformation of SSH under the low-velocity impact, enhances plateau stress, and makes a rhombus-shape band forming near the impact end. The results of finite element simulations show that SAH can absorb much more energy per unit mass than SSH under different impact velocities. Furthermore, the effects of the relative density and the impact velocity on the plateau stresses of SAH were discussed, and the empirical formula of plateau stress of SAH is given.
