Determination of CTOD C in Fibre Metal Laminates by ASTM and Schwalbe Methods [PDF]
Materials Research, 2002 Fibre Metal Laminates (FMLs) have arisen as a demand of the aeronautical industry to use thin sheets with high resistance to fatigue crack growth, high damage tolerance, corrosion resistance and high specific strength.

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.

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

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.

Racial Differences in Left Ventricular Mass and Wave Reflection Intensity in Children
Frontiers in Pediatrics, 2020 The burden of heart failure is disproportionately higher in African Americans, with a higher prevalence seen at an early age. Examination of racial differences in left ventricular mass (LVM) in childhood may offer insight into risk for cardiac target ...

Low-cycle Fatigue and Fracture Behaviour of 9%Ni Steel Flux Cored Arc Welding joint at Cryogenic Temperature [PDF]
MATEC Web of Conferences, 2019 In the present work, low-cycle fatigue (LCF) test and crack tip opening displacement (CTOD) test were performed for 9% Ni steel flux cored arc welding (FCAW) joint at room temperature (296 K) and cryogenic temperature (80 K).

Advances in Civil Engineering, Volume 2025, Issue 1, 2025.Limestone or river aggregates have been traditionally used as aggregates in ready‐mixed concrete from the past to the present. The depletion of these natural aggregates used in ready‐mixed concrete has led the concrete industry to investigate aggregate resources and search for alternative aggregates.
