Fatigue life estimation of self-piercing riveted aluminum joints under mixed-mode loading
International Journal of Fatigue(2017)
摘要
•A special jig was designed to evaluate the fatigue strength of the SPR joints.•A cross-shaped specimen was adopted to measure the fatigue strength.•Effective stress intensity factor is appropriate for evaluating the fatigue lifetime.
