Conventional fracture mechanics have made it possible to quantify the slow propagation of a crack subjected to cyclic loadings,as well as the fracture phase. Unfortunately,it is still impossible to quantify seperately the initiation phasc of a crack. Fatigue crack initiation was investigated by testing 2124T351 Aluminum alloy with 12 mm thick ASTM compact tension specimens having various notch-root radii between 0.1 and 10 mm . Crack initiation was detected by electric potential method. In order to calculate the number of cycles required to initiate a crack,notch root behavior was investigated through two main approaches: Elastic and Elastoplastic analy-sis of stress concentration under fatigue. The effect of confined plasticity at the notch root was analysed. Consideration of this plasticity would ameliorate to a great extent the crack initiation analysis and prediction.
