In this article, a finite element analysis of hollow tubes made of aluminum alloy 6060-T4 is used to investigate the energy absorption and collapse behavior with different corrugated section geometries.Abstract:
Abstract With the help of finite element analysis, this research paper deals with the energy absorption and collapse behavior with different corrugated section geometries of hollow tubes made of aluminum alloy 6060-T4. Literature available experimental data were used to validate the numerical models of the structures investigated. Based on the results available for symmetric crushing of circular tubes, models were developed to investigate corrugated thin-walled structures behavior. To study the collapse mechanism and energy absorbing ability in axial compression, the simulation was carried in ABAQUS /EXPLICIT code. In the simulation part, specimens were prepared and axially crushed to one-fourth length of the tube and the energy diagram of crushing force versus axial displacement is shown. The effect of various parameters such as pitch, mean diameter, corrugation, amplitude, the thickness is demonstrated with the help of diagrams. The overall result shows that the corrugated section geometry could be a good alternative to the conventional tubes.read more

TL;DR: In this article, the effects of buckling under oblique loading were analyzed and the linear buckling code was used for finding the critical buckling load, which is the process in which the tube is subjected to compressive oblique load and the tube fails by the first increase in crossectional area and then bulging on any of the sides.
