| Abstract: | The initiation/propagation behaviour of small surface fatigue cracks were investigated experimentally for # 35 steel specimens. The results showed that the microstructural size and distribution will greatly affect the initiation/propagation behavior of small cracks,and both the lives of initiation and propagation can be expressed quantitatively by Weibull's distribution. |
