| الوصف: | Fretting fatigue is a common structural failure phenomenon. It can greatly reduce the fatigue life of a structure, and because of the complexity of its load condition, it is a challenging research topic. This paper applies, for the first time, the widely used stop hole repair technology to a fretting fatigue specimen in crack propagation stage in order to extend its lifetime. LEFM approach is adopted for the crack propagation phase using Paris' law to predict the fatigue life. The critical plane parameter and variable length critical distance method are used together to predict the second crack initiation lifetime. This prediction method is validated by the central crack tensile fatigue experiment, which considers the stop hole. It is shown that the stop hole changes the propagation path and leads to a secondary crack initiation from the lower edge of hole. The increase of crack propagation life mainly comes from the secondary crack initiation. It is also found that the larger the radius of the stop hole, the greater the fatigue life is. |
