This paper presents an original approach to predict fatigue crack growth (FCG) under complex loading. Two FCG models based on damage accumulation by cyclic plasticity were developed with this aim. The crack growth is associated with the sequential failure of volume elements ahead of the crack tip, which is assumed to be caused solely by the cyclic plastic deformations induced by the loading. A complex random load history, counted by the sequential rain-flow method implemented in the VIDA 2001 software, was used to test the models. Predictions of crack size increments based on the proposed models were compared with those obtained by the direct integration of the material's da/dN curve using the cycle by cycle method.
