Design, fabrication and economy of welded structures

Abstract

This article deals with the deformation specialities of aluminium circular tubes. These tubes could be used to absorb energy of collisions. For example in a test rig created to measure and test seat belts a batch of tubes slow down the test rig and simulate the deformation of a car chassis. Circular tubes with the same cross section and tube length parameters made of three different aluminium magnesium alloys were analysed by finite element method to determine the effect of increasing yield strength values on energy absorbed.
