Up to now, with a probabilistic point of view (i.e., Weibull law), models account for the stress heterogeneity effect by introducing the concept of effective volume. It is proposed to extend this concept to multiaxial load histories. It consists in introducing a factor representing the distribution of activated slip directions. The non-proportionality effect is taken into account with no additional parameter with respect to traditional (i.e., Weibull) probabilistic approaches. The proposed model is validated on a large experimental data base and compared with other models. %G English %L hal-00497859 %U https://hal.science/hal-00497859 %~ ENSTA-BRETAGNE %~ UPMC %~ CNRS %~ ENS-CACHAN %~ ENSTA-BRETAGNE-LBMS %~ LMT %~ SORBONNE-UNIVERSITE %~ SU-SCIENCES %~ FARMAN %~ ENS-PARIS-SACLAY %~ ALLIANCE-SU %~ LMPS
