Crushing Behavior

The paper presents the results of numerical tests of impact and energy absorption capacity of thin-walled columns, subjected to axial impact loading, made of aluminum alloy, and having a square cross-section and spherical indentations on their lateral surfaces. The numerical models were validated using an experiment that was conducted on the Instron CEAST 9350 High Energy System drop hammer. Material properties of the applied aluminum alloy were determined on the basis of a static tension test. The crushing behavior of the columns and some crashworthiness indicators were investigated. On the basis of the results of the conducted analyses, conclusions were drawn about the most beneficial design/constructional variants in terms of achieved crashworthiness parameters.

Dynamic Crushing

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.
