Abstract：

The process of self-pierce riveting with solid rivet was simulated by FEM software Deform-2D. The distribution and developing trends of damage were analyzed. The result shows that the cross section of simulation is in agreement with the experimental result. The filleted corner was used in the transition between the head and shank of rivet. The geometry optimization of the rivet made the distribution of the stress more reasonable. Several factors including clamp force,clearances and corner radius were optimized. The proper parameters reinforced the quality and performance of the joint.
