Convenient method for estimation of JIC by CTOD.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series A, 1985 The JSME standard (S-001) for determination of JIC recommended to draw the blunting line or to measure the stretched zone width by an electron microscope. However, this procedure is taken trouble to measure these values. Following the British Standard BS5762, the CTOD value, Φi, at the onset of the ductile fracture is determined by using the CTOD ...

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.

The 1/r singularity in weakly nonlinear fracture mechanics
, 2009 Material failure by crack propagation essentially involves a concentration of large displacement-gradients near a crack's tip, even at scales where no irreversible deformation and energy dissipation occurs. This physical situation provides the motivation
