The effect of hydrogen on the fracture toughness of friction‐stir welded API 5L X70 pipeline steels
Fatigue &Fracture of Engineering Materials &Structures, Volume 45, Issue 10, Page 3009-3024, October 2022., 2022 Abstract The hydrogen embrittlement (HE) leads to severe steel degradation of mechanical properties. The hydrogen atoms diffuse into the steel and get positioned into reversible and irreversible trap sites. The pipe to transport oil and gas needs to be welded to construct long‐distance pipeline projects; thus, friction‐stir welding (FSW) has proven an ...

Fatigue Crack Growth from Notches: A Numerical Analysis
Applied Sciences, 2020 A numerical approach based on plastic crack tip opening displacement (CTOD) was followed to study fatigue crack growth (FCG) from notches. The identification of fundamental mechanisms was made considering notched and unnotched models, with and without ...

Characterisation of the crack tip plastic zone in fatigue via synchrotron X‐ray diffraction
Fatigue &Fracture of Engineering Materials &Structures, Volume 45, Issue 7, Page 2086-2098, July 2022., 2022 Abstract This paper describes a new methodology for characterising the plastic zone ahead of a fatigue crack. This methodology is applied to a set of experimental data obtained by synchrotron X‐ray diffraction on a bainitic steel compact tension specimen.

Fatigue &Fracture of Engineering Materials &Structures, Volume 45, Issue 5, Page 1494-1504, May 2022., 2022 Abstract A growing fatigue crack gives rise to a plastically deformed wake of material that envelops the crack. In this work, the plastic wake extent during fatigue crack growth is experimentally quantified by analyzing the crack tip displacement fields measured with digital image correlation.

Purity Effect of High‐Strength Steel on Failure Behavior of Automobile Front Axle
Advances in Materials Science and Engineering, Volume 2022, Issue 1, 2022., 2022 As unpredictable fracture of the front axle will lead to serious safety accidents, its failure behavior study is essential. This paper analyzes typical cracks on I‐shaped and leaf springs of the front axle made by Steel A and Steel B. Steel B has a lower content of S, N, Cu, and Sn than Steel A.
