Experimental Study on The Bending Collapse Characteristics of Aluminum Rectangular Tubes

알루미늄 사각관의 굽힘붕괴특성에 관한 실험적 고찰

In this paper the bending collapse characteristics of 6XXX series aluminum rectangular tubes were studied with a pure bending collapse test rig which could apply the pure bending moment without imposing additional shear and tensile forces. Under the pure bending moment, there occured three kinds of bending collapse modes-local buckling delayed buckling and tensile failure-depending on the a, b, t (depth width thickness) and material properties. Experimental results are compared with the results of finite element method and other methods.
