Enhancements of a Stress-Based Approach for Fatigue Life Estimation of Multi-Material Connections Joined by Self-Piercing Rivets and Adhesive

Due to the continuously reduced emission targets from legislation, lightweight constructions are getting more and more important for car manufactures. One way to reduce weight is the use of multi-material design for the body in white where new joining technologies, such as self-piercing rivets (SPRs) need to be considered instead of spot welding. Since both spot welds and SPRs are local circular joints, it appears reasonable to adapt and modify...
