Box-Beams are generally representative of primary load-carrying components in vehicle structures during frontal crash events. Bending and buckling of these components is the method whereby most of the impact energy is absorbed. In this paper, the axial crush behavior of a rectangular tube has been analyzed numerically using the non-linear finite element code LS-DYNA3D. The finite element model was validated by comparing the crush behavior of a steel tube with published experimental work. The effect of Mesh density as well as the type of shell are also considered. Aluminium, and carbon based composite materials are also used in the finite element model. The energy absorption capability as well as the peak crush load capacity for these three materials are studied and a comparable analysis considered. Based on the results of the analysis, guiding recommendations are provided in the context of improved accuracy with reduced computational cost.
