Statistical modeling of fatigue crack growth rate in Inconel alloy 600
KS Al-Rubaie, LB Godefroid, JAM Lopes - International journal of fatigue, 2007 - Elsevier
Inconel alloy 600 is widely used in heat-treating industry, in chemical and food processing,
in aeronautical industry, and in nuclear engineering. In this work, fatigue crack growth rate
(FCGR) was evaluated in air and at room temperature under constant amplitude loading at a
stress ratio of 0.1, using compact tension specimens. Collipriest and Priddle FCGR models
were proposed to model the data. In addition, these models were modified to obtain a better
fit to the data, especially in the near-threshold region. Akaike information criterion was used …
