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 ...

THE NON-CONSTANT CTOD/CTOA IN CRACK PROPAGATION [PDF]
, 2020 Unlike the common belief that crack propagation behavior can be predicted successfully by employing fracture criteria based on a constant crack tip opening displacement or angle (CTOD/CTOA), this paper shows that the initially non-constant portion of the

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.
