Axial Crushes Simulation of Thin-walled Square Aluminum Alloy 6061-T5 Foam-filled Section

Abstract

This paper deal with numerical study of the dynamic impact of axial crushing on thin-walled extrusion aluminum alloy 6061 and polystyrene foam-filled tubes square cross-section. Non-linear dynamic-impact simulation was done using finite element software's package as well on foam-filled model. Non-linear dynamic finite elements were carried out to simulate buckling and crushing phenomenon in the crushed event. Influence of fillers on the energy absorption behavior of square and thin-walled metal tube extrusion aluminum alloy 6061 estimates empty and foam-filled examined. Three main decay modes have been identified for the model is crushes, for example, diamond compound symmetry, axisymmetric concertina mode of formation and mixing times. Three different arrangement foam-filled inner tube columns has been examined and investigated.
