Fatigue test rig is a mechanical instrument helps to find out the fatigue strength of a material. Fatigue is considered as the single largest factor which causes failure of metals. An approximate of 90% metallic failures iscaused by fatigue. Due tothe non-homogeneity and an-isotropic properties of composite materials, it is very complex to predict the behavior of these materials subjected to fatigue load. So it is very essential to get a clear idea about the fatigue behavior of a composite material. Designing and modelling an apparatus of low cost fatigue test rig aided with an electric motor and load was applied gradually to determine fatigue strength ofthematerial.
