| Abstract: | Based on two\|dimensional probabilistic Miner's rule (TPMINER), A new method of reliability\|based prediction of fatigue life is established for structural components subjected to gust loading spectrum. The experiment verification is performed by using a set of fatigue testing results of LY12\|CZ aluminum panel specimens with a central hole. It is showed that the predicted values of fatigue life agrees very well with the test data, indicating that this new prediction method is very useful and important in engineering application. |
