AB This study presents a detailed analysis of a fatigue test campaign in order to identifydifferent crack patterns. It was conducted on 6061-T6 aluminum tubular specimens featuring aninternal diameter of 10mmand different thicknesses (2, 3 and 4 mm). These specimens were subjectedto cyclic tensile loads with a load ratio of R = 0.1, utilizing a sinusoidal load function at a frequencyof 3 Hz. The investigation examines the crack growth rates, the stress intensity factor, and thefinal and intermediate fracture zones by applying overloads in some cases. The differences withtwo-dimensional specimens and the importance of this study for the interpretation of results withbiaxial loading states are highlighted. The different states of crack growth detected are analyzed usingartificial vision techniques. The differences between the exterior and interior faces of the specimenare revealed, and a series of states prior to the formation of the radial crack front expected in thesespecimens are identified.
