Thin-walled tubes have been developed and are growing in use as new energy absorber structures. The objective of this study is to investigate the energy absorption and crushing characteristics of corrugated tubes with different number of corrugation in a specific length exposed to lateral loading. At the first step, experimental tests were carried out on a corrugated tube with three corrugations (two inner and one outer) and a tube without corrugation. After that, a finite element model was developed by means of ABAQUS software in order to study the effect of corrugation number on crushing properties of thin-walled tubes. The results show that tubes with corrugations have a higher mean crushing force which is directly proportional to the number of corrugations. Moreover, the plateau region in load-displacement curve decreases by increasing the number of corrugations and therefore the tube reaches its densification point earlier. Plastic strain variation pattern along the tubes were investigated as well.
