... load tests have also been performed to investigate the influence of crack depth on the threshold stress intensity factor for stress corrosion cracking ( K ISCC ) . Preliminary results suggest that in this case there is no crack depth dependence in the range of flaw sizes tested. While further...

...John A. Beavers; Brent A. Harle This paper provides an overview of mechanisms for high-pH and near-neutral pH stress corrosion cracking of underground pipelines. Characteristics and historical information on both forms of cracking are discussed. This information is then used to support proposed...
