Abstract
Prediction of Fatigue strength micro-specimen of non ferrous materials such as aluminum and copper alloys materials has been investigated using micro-fatigue testing machine under rotating bending load. The test was carried out at various specimen diameters such as 1 and 2 mm. The results show that the fatigue strength for micro-specimen with diameter of 1 and 2 mm for copper alloy material was higher than of aluminum alloy material. The fatigue strength for specimen diameter of 2 mm was higher than of specimen diameter of 1 mm. In addition, when compare the fatigue strength of copper and aluminum alloys materials was lower than of fatigue strength of steel materials.
