Abstract

Increasing public demand for better fuel economy has led the automotive industry to use more aluminum components in vehicles. The present study deals with the problem of joining aluminum structural panels and examines the tensile test results of resistance spot welded and self-pierced riveted aluminum joints. It investigates the effect of combining these two technologies with the adhesive bonding technology, resulting in "hybrid joints". A "peak-by-peak" analysis approach assesses the relative contribution of each joining element to the overall performance of the joint. Stress analysis was performed to define the failure criteria for the joining elements; tentative engineering design rules are proposed. The impact of the presence of adhesive on the spot welding and riveting process has been evaluated. Optimal joining solutions are recommended.
