Purpose: The purpose of the paper is to presents a study of the energy absorption of square tubular structures. Design/methodology/approach: Tubes of three materials namely, mild steel, glass reinforced composite and Kevlar reinforced composite were used to observe their deformation and energy absorption characteristics. The tubular structures energy absorption characteristic was reviewed from both the materials and structural points of view. Axial crushing tests were carried out on the tubes under quasi-static loading condition. Findings: The load-displacement curves of the tested tubes were presented and described. In addition, the deformation processes of the tubes was analyzed and evaluated. Several fracture modes of the crushed tubes were observed in most cases. Research limitations/implications: It has been found that parameters such as thickness, type of fiber and length of tubes has a considerable effect on the crushing characteristic of collapsed tubes. Originality/value: Description of crushing behavior of the energy absorption characteristic of glass/polyester and Kevlar/polyester thin-walled composite square tubes under quasi-static axial crushing load.
