摘要：

The propagation of microcracks on the level of grains in polycrystalline ductile materials was examined, leading to what is commonly called `failure by fatigue'. The stress intensity factors were computed for the fatigue threshold by means of shakedown analysis. The linear functional relationship observed between the shakedown stress intensity factor and the diameter of the grain of the examined materials is discussed.
