Statistical Analysis of Fatigue Crack Growth Rate of Q345E Steel

Abstract:

Experiments of fatigue crack growth rate were conducted for standard compact tension specimen of Q345E steel; the resulting experimental data were processed by the use of incremental polynomial method for mathematical statistical analysis. The crack growth rate formula can be obtained under different survival rates by the use of Pairs Formula.
