Abstract:
The experimental studies on the static and dynamic mechanical properties of aluminium
foam material are presented first. Finite element models of four structures, including circular tube filled and bonded with aluminium foam, circular tube filled but unbonded with aluminium foam,
single aluminium foam column and empty aluminium tube, under dynamic transverse compression are established by FEMB code. The dynamic mechanical behaviors of the structures are analyzed
using LS-DYNA finite element code. The simulating results at certain cases are compared with experimental measurements and the satisfying consistency confirmed the validity of the model. The
further numerical simulations are carried on the dynamic mechanical behaviors of four structures with outer tubes of different wall-thickness. It is found that aluminium foam filling can greatly
improve the load-bearing capacity and energy-absorbing efficiency of structures. On the other hand, the effect of the aluminium outer tube on the structure is obvious compared with single aluminium
foam column, in spite of the foam core and the tube are bonded together or unbonded. Another result can be seen that the bonding between the foam and outer tube affects the structure weakly for
both thinner and thicker tubes. Finally, the simulating results show that the thicker wall of tube can improve the load-bearing capacity and energy-absorbing ability of the structure.
