Experiments were performed to study the energy absorption efficiency of axially crushed aluminum circular tube. Axisymmetric buckling has the advantage in efficiency of energy absorption. Then, axisymmetric buckling is induced by using the jig, which restricts the radial inside. It was shown that the friction between the jig and the tube as well as the trough shape of the load displacement is available to improve the energy absorption efficiency.
