Resumen: Finite element and local strain approach predictions of cyclic stress-strain were investigated for five different types of notched AlCu4.5Mn specimens. Concentration factors for each specimen were determined and compared with those available in literature. Average values and ranges for both elastoplastic stresses and strains were obtained, for several fully-reversed and pulsating nominal traction loading conditions, using non-linear finite element modelling. The obtained results were thoroughly compared and discussed.
