Fatigue life prediction for cracked parts with the classical finite element method is not an obvious task for industrial structures. Indeed, it is necessary to take the crack geometry into account (its surfaces and front) with enough accuracy. The stress intensity factors (SIFs) are then computed and the crack can be propagated. Consequently, a remeshing step is necessary for the next time step’s mechanical problem. These remeshing procedures are difficult in 3D and are very time-consuming.
