الوصف:
It is necessary to identify relationship between the fatigue crack propagation rate and the stress intensity factor range, if the fracture mechanics approach is applied to evaluate the fatigue crack growth evolution. In addition, identification of the stress intensity factor range of fatigue crack growth threshold (ΔΚ_) is important to evaluate the structural integrity from the view of fatigue performance. / ASTM standard E647 "Standard Test Method for Measurement of Fatigue Crack Growth Rates" is widely known as a de fact standard to determine the value of ΔΚ_. However, a considerably long time is required to perform the determination of ΔΚ_ value. Therefore, it is expected to cut the experimental period for ΔΚ_ determination. / Efficient and time saving procedure for determining ΔΚ_ value comparing with ASTM-E647 is proposed in this study. Many fatigue crack propagation test data were applied to verify the validity of our proposed method. It is expected to be able to complete the experiment for determining ΔΚ_ value at a stage where the fatigue crack propagation rate is one order larger comparing with ASTM-E647.
