Impact of Environmental Hydrogen Pressure on Fracture Toughness and Fracture Behavior of X65 Pipeline Steel Welded Joints

Journal of Manufacturing and Materials Processing
Hydrogen embrittlement (HE) damages the fracture toughness, often promoting brittle fracture even at low stress levels. Since welded joints are sensitive to this kind of damage, there is a very high risk of failure.

Computing the stress intensity factor range for fatigue crack growth testing at 20 kHz

Engineering Reports, Volume 6, Issue 6, June 2024.
A comparative study on the computation of the SIF at 20 kHz load frequency. Results from different simulation procedures are presented and discussed. Abstract Inertia and damping influence the values of the stress intensity factors (SIFs) at high‐frequency loading and they must be included in computations.

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.

Calibrating an adaptive cohesive zone model to simulate ductile crack propagation in structural steel under cyclic loading

Fatigue &Fracture of Engineering Materials &Structures, Volume 47, Issue 2, Page 319-343, February 2024.
Abstract A procedure is outlined for calibrating a finite element model to simulate ductile cracking that employs a continuum damage criterion for ductile fracture initiation, termed the Stress Weighted Ductile Fracture Model, with an Adaptive Cohesive Zone method to simulate crack propagation.
