Abstract: The finite element simulations have been carried out to study the shortening behaviour in axial plastic deformation of square and circular tubes of equivalent cross section under axial impact by 350 kg falling weight hammer. 3D models of hammer and the tubes were made and numerical computations were done with ABAQUS/explicit solver. The influence of different diameter and size of hollow mild steel tubes on energy absorption and axial deformation under the axial impact were investigated. It was found that with the increasing of diameter and sizes of circular and square tube, the axial compression decreases. The energy absorption at different span, do not have significant difference. These tubes were found fully compressed at higher incidence energy. It was also observed that square tubes show the higher axial compression than circular tubes. The circular tubes revealed the higher absorbed energy than square tubes under axial impact.

Keywords: crashworthiness; geometric nonlinearity; axial deformation; energy absorption; J-C material model; mesh convergence study.
