Multiaxial fatigue damage modelling at Macro scale of Ti6AL4V alloy

[en] The Lemaitre and Chaboche fatigue model is investigated in order to predict the fatigue life of tensile samples with and without notches, defining different stress concentration fields. Elastoplastic FE simulations based on anisotropic yield locus description were carried out in order to obtain the stress and strain distributions near the notch root. The Lemaitre and Chaboche fatigue model was applied using the point method (local approach) and the gradient method (non-local approach).
