Abstract
Foam-filled thin-wall structures exhibit significant advantage in light weight and high energy absorption. Axial compression wes done to investigate the crash behavior of the empty and foam-filled cylindrical tubes. Non-linear finite element analyses were carried out to simulate the axial compression. The energy absorption capacities of the filled tubes were compared with the empty cylindrical tubes. The results showed that the energy absorption capability of foam-filled tube is higher than that of the combined effect of the empty tube and the foam alone. The reason is that the foam prevents the cylindrical tube from a natural deformation.
