摘要：

The test on fatigue crack growth rate of ADB610 steel is completed. The standard compact tension specimen is loaded by cyclic loading, whose stress ratio is constant at a value of R=0.1. Crack growth rates in the form of Paris formula at different survival levels are obtained by using three methods. After a simple comparison it is clear that crack growth rates obtained by three methods are generally same and the method based on (da/dN, delta K) has better effects on data analysis.
