Experimental study on the energy absorption capability of circular corrugated tubes under lateral loading and axial loading

Abstract: A new type of energy absorber called an expansion joint (i.e. a corrugated tube) is examined in this research. Several experiments are performed on three types of thin-walled specimen, namely circular tubes, preformed corrugated tubes and complete corrugated tubes, to investigate the energy absorption of steel specimens under different conditions for quasi-static lateral loading and axial loading. For this purpose, some steel specimens were compressed between two rigid platens in the axial direction, and the o… Show more

“…Taking into account the efficiency of circular tubes [17], the geometrical parameters of the circular tube chosen for the NS filler design were selected based on [10]. The model of the empty circular tube and then with a NS honeycomb filler was developed using the Solidworks 2014 3D CAD environment following the approach discussed above.…”

“…These structures are often tested using various loading methods such as axial impact, lateral indentation, lateral compression, splitting, and inversion. When subjected to axial loading, thin walled EAEs such as honeycombs, and circular and square tubes were found to perform optimally, absorbing marginally more energy than in other loading conditions [18,19,20,17]. Folding and buckling are found to be the most efficient way of deformation and maximum energy absorption [18].…”

“…Thin-walled structures are widely used as energy absorbers. 1 Some interesting characteristics of these structures are their low cost, simplicity, and, most importantly, their capacity to absorb large amounts of energy through plastic deformation. 2,3 In addition to these features and with the main objective of reducing CO 2 emissions, the lightness of the structural members is another strong requirement in the automobile industry.…”
