Abstract:Engineering components often fail due to fatigue when subjected to cyclic loading. A series of fatigue crack growth experiments were conducted using compact tension specimens of 316L stainless steel. The influences of the R-ratio and the tensile overloads were studied. The results show that the 316L stainless steel displayed sensitivity to the R-ratio. The crack growth rate increased with the increase of R-ratio. The application of a tensile overload resulted in a short period of acceleration in the crack growth rate followed by a significant retardation in the crack growth rate. The new two-parameter model was used to describe the R-ratio together with a modified Wheeler’s model to predict the crack growth behaviour after overload. The method mentioned can better describe the fatigue crack growth behavior of 316L Stainless Steel under different working condition.
