Abstract
This paper is aimed at investigating the parameter effects on dynamic crushing behavior of staggered Kelvin cellular metal using finite element method. The geometrical characteristics of the staggered cellular structure were analyzed and the finite element model was constructed using shell elements. A full factorial Design of Experiment simulation was carried out and four individual factors including two structure characteristics of the cellular metals and two mechanical parameters of the base material were selected, namely cell edge length, cell wall thickness, yield stress and tangent modulus. Their single and interaction effects on plateau stress, densification strain and densification strain energy were mainly researched. From the results it could be seen that the structure characteristics were a little more important than the base material properties for aluminum staggered Kelvin cellular metal.
