Study on Mechanical Properties of 6063 Aluminum Alloy Tube with Defects Under Impact Load

When aluminum alloy tube have defects, they may be damaged by lateral impact in practical applications. Based on the general finite element analysis software, dynamic and performance research of with without defects different diameter to thickness ratios velocities were conducted this paper. The results show that weak resistance are prone local damage. Reducing ratio can improve structure; when speed is same, due large tensile deformation at midspan defect, energy locally absorbed maximum displacement smaller than defects; larger velocity is, defect reaches mid-span peak same time, but enters stable stage faster.
