Fatigue Strength of High-speed Nailing Joint Using Spiral Nail

Abstract

Multi material manufacturing is progressing to achieve weight reduction. Mechanical joining techniques such as bolted joint and high-speed nails can be used for dissimilar materials joining. In our previous study, we developed the high-speed nail joining method using especial nail with double spiral grooves in the shank. In this study, we have assessed the fatigue strength of the spiral nail joint. And also the fatigue strength of blind rivet joint with same size as the spiral nail was assessed. Results showed that the fatigue strength of the spiral nail joint was the same as that of blind rivet.
