<p>In many numerical prediction and experimental studies, the cyclic uniaxial loading model is the most frequently analyzed, but in real and probable cases, most of these structures are no longer loaded uniaxially. By using the finite element method and the ABAQUS calculation code, the novelty in this work is presented in the loading modality where the notch itself is in strong cyclic biaxial loading, which is the likely case in reality is at levels sometimes severe and complex that accelerate the damage of these structures the numerical prediction in this work has followed an approach that consists in formulating the fatigue behavior under the equivalent Von Mises flow stress by the combined hardening law, with scaling according to the concepts proposed by the homogenization laws or damage is given in adequacy by the XFEM (Extend Finite Element Method) technique to predict and visualize further crack initiation and propagation in the structure, the reliability of these numerical prediction results precedes an experimental comparison in simple ungraded cases subjected to uniaxial cyclic loading, showing good agreement in the cyclic response. Three different cases of biaxial cyclic loading are then applied to the numerical model. The numerical results show that the biaxial cyclic loading path, with and without scaling, significantly affects the ductility and strength of these structures.</p>
