Kurzfassung:
Material damage state is described by a restraining stress zone. Then, a macro/micro trans- scale fatigue crack growth model is established. The proposed model is used to simulate the whole fatigue process from a micro-defect to the final macroscopic fracture. Numerical calculations are performed. The fatigue test data for the LC4 aluminum alloy plate specimens are accurately re-produced by the present model. Furthermore, when the microscopic effects are taken into account, the scatter feature of the fatigue test data can also be reflected.
