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.

A Structural Integrity Perspective for the Assessment of Ageing in Composite Solid Propellants

Propellants, Explosives, Pyrotechnics, Volume 50, Issue 10, Page 152-158, October 2025.
ABSTRACT Composite solid propellants (CSPs) are critical materials in the defence and aerospace industries, known for their complex mechanical behaviour and susceptibility to ageing. This study explores the application of Principal Component Analysis (PCA) to discriminate the ageing degradation of CSPs based on structural integrity parameters.
