Abstract

Based on experimental observations on 7010 Aluminum alloy recalled in the first part, a fatigue crack growth modeling is proposed. The model deals with the possibility that a crack has to intergranularly deviate when it encounters a grain boundary. It appears that short cracks are more subjected to bifurcation than long cracks and that globally crack propagation tends to remain in mode 1. Finally, the cycle number to rupture is computed as a function of microstructural parameters.
