Abstract
We carried out fatigue testing with materials of aluminum alloy(7075-T6, 2024-T4) by rotary bending fatigue tester. We investigated fatigue limit, fatigue crack initiation, fatigue crack propagation behavior and possibility of fatigue life prediction to the different small circular hole defect. The summarized result are as follows ; Fatigue limit of the smooth specimens were related tensile strength and yield strength. In case of more large...
