Abstract:Abstract. This paper deals with the dynamic response and energy absorption of foamlled aluminum parabolic tubes under axial impact loading. The numerical crush analysis of empty and foam-lled tubes is performed using non-linear nite element techniques. The e ects of geometrical (wall thickness) and material parameters (foam density and Young's relaxation modulus) on the impact response and energy absorption capacity of foam-lled tube are investigated using numerical models. The results show that the foam prope… Show more
