Aim of this paper is to predict the fatigue strength of welded joints by means of fracture mechanics approach that takes into account the fatigue behavior of short cracks. The methodology helps to find out the fatigue crack propagation rate as a function of the difference between the applied driving force and the material threshold for crack propagation, a function of crack length. Analytical fatigue models were developed to estimate the fatigue behavior of notched plates. The analytical results obtained were compared to that with FEA to predict its life

Keywords: fatigue, crack growth, stress concentration factor.
