Abstract :
This paper deals with the dynamic response and energy absorption of foam-
lled 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 Youngʹs
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 properties
have signi cant e ect on the crushing behavior, force and impact acceleration magnitude,
and energy absorption capacity. Furthermore, there is a critical foam density beyond which
the structure loses its energy absorption performance. Experimental results acquired from
a test setup are used for validating the Finite-Element Analysis (FEA). There is good
agreement between numerical and experimental result
