The main aim of this work is the fatigue strength assessment of butt joints with weld reinforcement, typically used in steel works and especially in shipbuilding applications. A sensitivity analysis has been carried out by varying different geometrical parameters of the welded joints. Moreover, two different approaches for fatigue strength estimates were applied, namely the Effective Notch Stress Approach, which is nowadays widely used and it is supported by comprehensive literature and the Strain Energy Density approach. Analyses were carried out using two different finite element codes: Ansys® and Adina®. The application of different software allowed verifying the quality of obtained results, disclosing certain essential aspects related to the extrapolation of values from integration points of finite elements.
