This paper presents the crushing behaviour of empty and foam-filled conical aluminium alloy (AA6061-T6) tubes under oblique impact loading using a validated nonlinear finite element (FE) code, LS-DYNA. The study aims to assess the beneficial of foam filling on the energy absorption in terms of mass reduction, for variations in filler density and geometrical parameters of AA6061-T6 tubes. The results obtained successfully identified the critical tube mass and critical foam density. It is evident that foam filling successfully induced high Specific Energy Absorption (SEA) value of foam-filled tubes thus proving that the assessment of critical total tube mass and critical foam density point is vital in identifying proper combination of tube-filler to the effectiveness of foam-filled tubes. The combination of AA6061-T6 tube and aluminium foam demonstrates pronounced SEA increase as high as 72.3% compared to the empty tube.

This paper reviewed the crashworthiness of foam-filled thin-walled structure subjected to oblique loading conditions. Crashworthiness is the most important part in designing a safety vehicle, so, the types of collisions, crashworthiness parameter and the modes of collapse of structural components are included in this part. Secondly, the energy absorber regarding the axial loading and oblique loading in terms of geometry parameters and materials of the previous research is reviewed. In addition, the manufacturing and properties of aluminium foams with the collapse behavior of foam-filled structures are studied to understand the performance and the relation under loading.
