Tension-tension fatigue behavior and its modelling for life estimation of rivet-bonding CFRP/CFRP single lap joints

Experiments of tension-tension fatigue were performed for rivet-bonding CFRP/CFRP joints in this work. The F-N curve was presented and the fatigue life was estimated. The failure modes of the joints under static tension and fatigue tension were compared. Hysteresis phenomenon was analyzed. Stiffness degradation and residual slip due to cycle loading-unloading were discussed and modeled by two non-linear expressions. The results demonstrated that...
