Crushing Behavior

The concerns of automotive safety have been given special attention in order to reduce human fatalities or injuries. One of the techniques to reduce collision impact or compression energy is by filling polymeric foam into metallic tubes. In this work, polyurethane foam was introduced into the steel extrusion tubes and quasi-statically compressed at constant cross-head displacement. Different tube thicknesses and foam densities were used and these parameters were related to the crashworthiness aspect of the foam-filled structures. It is found that both tube thickness and foam density played an important role in increasing the crashworthiness behaviours of the structures but when the tube thickness reached certain value, foam density unable to properly work in increasing the energy absorption of the structures.

The axial crushing of thin-walled tube has better energy absorption capability. Thus, introducing milled geometrical shapes on thin-walled tube may improve the energy absorption performance. The improvement of the crush response is determined through the reduction of the Initial Peak Force (IPF) and the increase of the Specific Energy Absorption (SEA). This was done by employing origami pattern milled on the surface of thin-walled square tube which was investigated experimentally and numerically. The material used for the tube was aluminum alloy 6063-T5. The simulation results were validated by experiments which were conducted using <span style="text-transform: uppercase;">Instron</span> 3382 Universal Testing Machine and <span style="text-transform: uppercase;">Instron Dynatup</span> 8250 Drop Hammer Machine. The numerical simulation then progressed by varying parameters such as dimensions and configurations of the origami pattern on the square tube. ABAQUS finite element (FE) software was used to conduct the numerical simulation. The result of employing the origami square pattern on square tube is expected to improve the crush response by lowering the IPF and increasing the SEA. The obtained results were then compared with the conventional square tube where the origami pattern on square tube enhanced the crush performance.</span>
