Abstract

The detail fatigue rating (DFR) value of riveted lap joints made of 2198-T8 aluminum-lithium alloy was measured and calculated based on the fatigue test results. Fatigue fracture surface morphology was examined by scanning electron microscopy (SEM). The results indicate that DFR value of 2198-T8 alloy is 83.09MPa. Fatigue fractography shows that the fatigue striations of 2198-T8 are smooth and neat, so 2198-T8 alloy have superior fatigue properties. The study can be used to select suitable materials from the fatigue strength design and fatigue life evaluation of the civil aircraft.
