The fatigue crack growth behavior of hydrogenated 9Cr‐1Mo steel: An experimental and numerical study
Fatigue &Fracture of Engineering Materials &Structures, Volume 47, Issue 5, Page 1677-1695, May 2024.Abstract This research investigates the fatigue crack evolution in P91 steel through experiments and extended finite element method (XFEM) simulation for as‐received and hydrogenated conditions. Hydrogen pre‐charging is performed using a constant current electrochemical method in 1 M sulfuric acid solution.

Object Grating Method Application in Strain Determination on CTOD Tests
Strain, 2006 Abstract: Standard fracture toughness tests require standard specimens with the presumption that mechanical properties are uniform in the crack growth direction. Standards for crack tip opening displacement (CTOD) fracture tests prescribe remote crack mouth opening displacement, which can lead to inadequate results in the case of heterogeneous ...

Influence and evaluation of constraint on fracture toughness in pipeline research [PDF]
, 2012 Accessing nowadays fossil fuel reserves requires a strain-based design approach. Within such design, the ductile tearing resistance is a key parameter in assessing the defect tolerance. To determine this tearing resistance, full scale (pressurized) tests
