For the usual failure mode of structural components under variable loading, fatigue life prediction is very important for the selection, design, and safety assessments of these components. The linear damage model (Miner´s rule) is used most widely for life prediction in practical engineering application. However, the fatigue damage caused by small loads cannot be ignored, especially when the load is near the constant amplitude of fatigue limit of a component. In the paper we use grey model to predict fatigue Life. The model improves the application of the traditional Miner rule, by considering the damaging and strengthening of low amplitude loads, under low amplitude loading strengthening.
