Analyse de l'influence des déformations plastiques dans les processus de fissuration et de fatigue par simulation numérique

Abstract : This work uses the numerical calculation to take into account the plastic deformation in fracture mechanics. We can verify the results of Rice on the extent of the plastic zone, taking into account work hardening. We then studied problems related to crack propagation under monotonic loading on the one hand, under cyclic loading on the other. In the third chapter, we verify the theoretical estimate of the force due to the singularity at the crack tip. This can also reveal a reduction of the opening relative to the elastic case, which explains the phenomenon and the free edges of cracks in fatigue. A final section applies the previous results in fatigue.
