“…The strain histories play an important role in determining the energy absorption. Avalle and Belingardi [6] experimentally obtained the strain histories for a circular tube under axial loading. The present study is an experimental measurement of deforming material by fitting the strain gauges in the outer faces of a mild steel hexagonal tube.…”

This paper presents an experimental study on the load-displacement curve and strain histories of a single hexagonal tube under quasi-static axial compression. The result is compared with computer simulation.The strain gauges are glued on to the outer faces, and both axial and circumferential strains are measured at a sampling rate of 40 readings every one second. The measured strains are examined both as time histories and as deformation fields. The response of hexagonal tube subjected to axial loading is observed through experiments. The FEA strain-displacement curve agrees well with the experiment if the gauges are away from the top of specimen.

“…Study on collapse characteristics of strength members like side members that receive axis loading is conducted in parallel with other studies on developing structural members with various materials and diverse cross-sectional shapes that can absorb lots of energy together with the light weight of vehicles for the purpose of safety performance. [1][2][3][4][5][6][7][8][9][10] With development of aluminum alloy in the early 20th century, a light-weight technique was progressed rapidly. These researches have been progressing as the needs for highly functional material such as composite material increases.…”

This paper investigates the crashworthiness of aluminum/CFRP hybrid members subjected to axial loads as changing CFRP stacking condition. Aluminum members absorb energy by stable plastic deformation, while CFRP members absorb energy by unstable brittle failure with higher specific strength and stiffness than those in the aluminum member.In an attempt to achieve a synergy effect by combing the two members, aluminum/CFRP hybrid members were manufactured and collapse tests were performed for the members. The stacking condition related to the energy absorption of composite materials is being considered as an issue for the structural efficiency. Therefore, the collapse tests were performed with change of the stacking condition. Test results showed that the collapse of the aluminum/CFRP hybrid member complemented unstable brittle failure of the CFRP member due to ductile nature of the inner aluminum member and the stacking condition of aluminum/CFRP hybrid members influence energy absorption capability and collapse mode.
