| Abstract: | WT5”BZ〗In recent years,increasing attention is being given to structure design and analysis method based on reliability in the important fields ,such as aeronautical,astronautical and nuclear reactor engineering ,for obtaining long life and high safety.Utilizing the probability analysis method ,we now present the probabilistic distribution of fatigue crack size for inspectable structure, which is one of the important factors in reliability model.The results may build a basis for establishing new fatigue reliability analysis model. |
