Aluminum tubes are efficient energy absorbing components and are widely used in the automobile industry.Many studies on the deformation of a circular tube have been done,but there are a few research reports on a square or polygonal tube deformation,such as the experiment of axial dynamic deformation and bending stiffness [1,2].In the previous report,the authors experimented on axial impact squeezing test of square tubes that had the reinforcing ribs in the cross-sectional [3].The influence of cross-sectional shape on axially compressed aluminum tube(square,pentagonal,hexagonal,heptagonal and octagonal)was investigated by compressive tests and numerical analysis [4].However,there are only a few reports on length of aluminum tube [4,5].
