英文摘要	Gradient porous structures are extensively studied in impact-resistant structures due to their light weight and high energy absorption. Different from existing studies, this article focuses on novel Voronoi structures with gradient perpendicular to impact direction, and compares their dynamic response with the uniform structure through numerical simulation. It shows that the novel gradient design comprehensively improves the impact resistance of Voronoi structures. Furthermore, density gradient is introduced into the one-dimensional shock model, and the theoretical solution of the plateau stresses at the impact end are compared with the simulation results, which verifies the correctness of the model in this article.
