Abstract (EN): One of the main problems of aeronautical structures is the onset and growth of damage due to fatigue loading. This phenomenon is accentuated in areas of stress concentration, for example in the connection of components, such as the riveted joints of fuselage panels. This paper is focused on the study of a single-lap splice with three rivet rows and one rivet column. A three dimensional stress analysis using the Finite Element Method was carried out to determine the stress intensity factors for a single crack and symmetric cracks starting from the edge of the hole located at the critical cross section. The obtained values were used together with experimental data in order to obtain the Equivalent Initial Flaw Size (EIFS) and then to predict the fatigue life of the specimen.
