Fatigue Crack Growth Behavior due to the Localized Compressive Deformation on Structural Steel

Fatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 5, Page 1597-1609, May 2026.
ABSTRACT The localized compressive deformation (LCD) process was used to analyze the fatigue crack growth behavior of a high‐strength low‐alloy structural steel. Eccentrically loaded single‐edge crack tension specimens (ESE(T)) in accordance with standard ASTM E647 were precracked at a crack length of about 4 mm from the machined notch by applying a ...

Influence of Surface Flaw Interaction on Failure Assessment Diagram in the Framework of Fitness‐for‐Service Procedures

Fatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 5, Page 1877-1894, May 2026.
ABSTRACT This study investigates the influence of closely spaced surface‐flaw interaction on failure assessment diagrams (FADs) used in fitness‐for‐service evaluations, addressing the conservatism introduced when standards such as BS 7910 and API 579 recharacterize interacting flaws as a single bounding crack.

Design and Development of an Accessible Clip Gauge Extensometer for CMOD Measurement in Fracture Mechanics

Engineering Reports, Volume 8, Issue 2, February 2026.
A low‐cost clip gauge extensometer for crack mouth opening displacement was developed from accessible procedures and materials. Accuracy and repeatability comparable to commercial devices were demonstrated in calibration and fracture tests, enabling reliable measurement in CT specimens for resource‐constrained laboratories.

Designing phase‐adaptive UHTC multilayer composites: Layer width effects on mechanical and kinetic properties

Journal of the American Ceramic Society, Volume 109, Issue 1, January 2026.
Abstract The B1 rocksalt transition metal carbides and nitrides are among the materials with the highest melting temperatures. Additionally, members of this group of materials possess high‐temperature strength with ductility facilitated by diffusional creep.

Prediction and Experimental Validation of the Influence of T‐Stress on I–II Mixed‐Mode Fracture in Rock

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
Traditional fracture criteria only consider the singular terms in the Williams expansion and neglect higher‐order term coefficients, resulting in significant discrepancies between predicted and measured values. To advance the understanding of rock fracture mechanisms, this study introduces a generalized maximum tangential stress (GMTS) criterion by ...

Influence of Notch Geometry and Temperature on the Mechanical Properties of Al‐Mg Alloy Using Molecular Dynamics Simulations

Fatigue &Fracture of Engineering Materials &Structures, Volume 48, Issue 11, Page 4769-4783, November 2025.
ABSTRACT At the near‐threshold regime, small irregularities on the surface can interact with the microstructure and affect the nucleation and propagation of cracks. Molecular dynamics is an effective methodology to investigate the damage evolution at this scale, and three types of defects, namely, triangular, rectangular, and crack, are examined.
