Resumen: In this paper cyclic stress-strain predictions using the Local Strain Approach and the Finite Element method in AIMgSi 1 alloy specimens were investigated. The stable hysteresis loops and the cyclic curve of the material were obtained experimentally using the 'one specimen for each strain level' method. Elastic Finite Element analyses were performed in order to determine the stress concentration factors of two different types of flat tension bar specimens: (i) with opposite semicircular edge notches and (ii) with shoulder fillets. These factors were compared with the ones available in literature. Local Strain Approach methods and elastic-plastic Finite Element analyses, considering both the kinematic and the isotropic hardening rules, were used to compute inelastic stresses and strains for severa! loadings of flat tension bar specimens with opposite semicircular edge notches. These results were compared and discussed.
