Crushing Characteristics on Square Tubes Under Progressive Buckling
https://orcid.org/http://orcid.org/0000-0002-5941-2494
This paper presented the research on crushing characteristics for progressive bucking square tubes under axial loading using the dimensional analysis method. According to the mechanical properties of mild steel and aluminium alloy, the finite element models of progressive buckling square tubes made up of different materials were established. Then dimensional analysis was developed to obtain the influence of inherent parameters on energy absorption characteristics of progressive buckling square tubes, and a theoretical prediction model was proposed to predict the energy absorption characteristics of progressive buckling square tubes subjected to axial loading. The theoretical prediction results were found to match well with finite element analysis and dynamic test results. Furthermore, the equivalence methods of square tubes made up of different materials and geometric parameters were discussed. The results showed that the equivalence of deformation displacement and equivalence of mean crushing force are better equivalence methods for lightweight design, and keeping a constant length and width to obtain an equivalent thickness for progressive buckling square tubes is a more stable equivalence method.
