This work compares fatigue analysis results presented in the literature with computational simulations performed using finite element software. To this end, two fatigue cases with distinct geometric configurations and loading conditions are analyzed. In the first case, the loading is multiaxial, with sinusoidal variation and the presence of a non-zero mean stress. In the second case, the loading presents alternating and mean stresses that vary over time, and is analyzed by counting load cycles using the Rainflow method. The results found in the literature for both cases, obtained through conventional theoretical fatigue approaches, are compared with the results of the computational simulations performed in this work using finite element software. It can be noticed that the use of numerical simulation computational tools offers great flexibility for the analysis of fatigue problems with complex geometries and loadings. Furthermore, the use of computational tools provides greater ease and speed in obtaining results, contributing to the development of more efficient designs.
