Elastic-plastic defect interaction in (a)symmetrical double edge notched tension specimens [PDF]

open access: yes, 2017
Interaction of defects tends to intensify their crack driving force response compared to the situation where these defects act independently. The interaction between multiple defects is addressed in engineering critical assessment standards like BS7910 ...

Full‐scale testing of near‐neutral pH stress corrosion cracking growth behavior of a vintage X52 oil pipe

open access: yesFatigue &Fracture of Engineering Materials &Structures, Volume 47, Issue 5, Page 1638-1655, May 2024.
Abstract This study presents an experimental investigation conducted on a 40‐year‐old vintage X52 oil pipe segment to assess the growth behavior of near‐neutral pH stress corrosion cracking (SCC). Six cracks were introduced on the pipe specimen, each of which was associated with a unique combination of metallurgical and environmental condition.
