dc.description.abstractThe advancement in friction stir welding (FSW) technology has provided automotive and aerospace industry with an alternative method in developing structures and assemblies. This study investigates the performance of FSW and gas metal arc welding (GMAW) on road vehicle bumpers. The method of investigation is to weld the bumper to the crash-box, and the assembly is mounted onto a moving deformable barrier before a dynamic crash test is performed. The bumper and crash-box is fabricated from AA6082-T6 and AA6063-T6 extrusions, respectively. In the first part of the study, the full-frontal crash testing of the FSW and GMAW fabricated bumper using experimental method is presented. The FSW and GMAW fabricated bumpers are subjected to 7, 10, 15 and 20 km/hr impact velocities against a rigid wall. The methods used to quantify the results are the post-crash deformation and stress distribution of the bumper as well as crack propagation at the weld joint. The non-linear dynamic software, LS-DYNA, is used exclusively in the second part of this study to replicate the experimental procedures using numerical methods. Finally, a 40% frontal offset test is conducted to evaluate the performance of the bumper when subjected to a different impact condition. It was shown that the FSW fabricated bumper can enhance the structural integrity and performance of the bumper at all impact velocities and configurations.en_US
