Interference-fit is a well-known technique for improving the fatigue life of joints

which has been widely adopted in aerospace manufacturing industry. The excellent performance of titanium alloy has greatly improved its application in aerospace structures. However

interference-fit riveting in our country is still limited to aluminum alloy structures

there is few studies on the interference-fit riveting in titanium structures. Fatigue experiments were carried out on titanium structures with different interference-fit levels in this paper. It was found that interference-fit riveting can greatly improve the fatigue life of joints compared with conventional riveting. The increment of fatigue life by interference-fit riveting becomes more obvious at lower level loads. Processing parameters

such as the gap between hole and pin

also have great effects on the fatigue life.
