Abstract
The need to create lighter vehicles to aid in reducing emissions and increase fuel efficiency has become increasingly important in recent years. Self-pierce riveting (SPR) has drawn more attention as it can join some advanced materials that are dissimilar and hard to weld. In present study, the SPR process has been numerically simulated using the commercial finite element (FE) software LS-Dyna. For validating the numerical simulation of the SPR process, experimental tests on specimens made of aluminium alloy have been carried out. The online window monitoring technique was used in the tests for evaluating the quality of SPR joints. Good agreements between the simulations and the tests have been found, both with respect to the force-travel curves as well as the deformed shape on the cross-section of SPR joint.
