The objective of this work is to propose a model to correlative two metodologies of fatigue design, the EN Method and the Linear Elastic Fracture Mechanics, traditionaly used in a separate way, to estimate the residual life of components subjected to estrutural fatigue.
For this purpose a model was built based on well estabilished hipotesis and limitations, where every step was explicitaly explained in detail.
Some improvement to the model were estabilished and their results evaluated.
Finally a comparasion between the curves generated by the models with the curves of experimental results of four materials, which mechanical properties were documentaded in especific literature, we confirm the vality of the proposed models.
