Aluminum alloys have a wide range of applications, such as the aerospace and automotive industries. The effect of V-notch on fatigue life of cylindrical beam made of aluminum alloys under rotating bending fatigue load has been investigated experimentally and numerically. The experimental work involved the tensile strength, hardness, impact test, and fatigue life behavior at room temperature. The fatigue life test was conducted with a fully reversed cycle with a mean stress ratio (R= -1). The experimental data were compared with the numerical result, and a good agreement was found. The results show that the notch has reduced the fatigue life of aluminum alloy beams.
