This paper is devoted to the presentation of a multiaxial fatigue damage model, derived from Chaboche’s uniaxial formulation. Fit for use in the entire range of crack initiation life, it takes a number of different effects into account, including mean-stress influence and cumulative damage under nonperiodic proportional and nonproportional loadings. Its identification and integration is described, and it is shown as a simple but efficient engineering tool. Several examples, taken from different authors allows us to validate this kind of model.
