A Comparative Study of Obliquely Positioned Aluminium Alloy 6063 Tubes under Axial Loading

Abstract:

A conventional tube is considered in oblique position when its longitudinal is oblique. However, oblique attachments vary as the tube can be a straight or angulated tube. In the present study, impact responses of different oblique positioned tubes subject to axial loading were numerically studied. Next, the best oblique arrangements were proposed that have higher critical load angle and energy absorption capacity. Results show that specimen of Top-Bottom Angulated (TBA) from horizontal is the best choice for its lowest initial peak load and mean crush load. This data therefore has great potential for further enhance the new design of energy absorbers in oblique position.
