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

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.

Estimation of the Fracture Probability Parameters for Specimens Made by JIS SM490A Steel
This work established the fracture probability equation for JIS SM490A steel using the computational model supported by the local approach and the standard Crack Tip Opening Displacement (CTOD) fracture toughness experiments.

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.

Phylogeny‐Aware Metabologenomics Accurately Assigns Natural Products to Biosynthetic Gene Clusters
We report a statistical approach for associating biosynthetic gene clusters with their cognate metabolites and demonstrate its unprecedented power for scalable natural product discovery. Notably, it drastically reduces spurious associations by explicitly integrating the phylogeny of microbial producer strains.

Racial Differences in Left Ventricular Mass and Wave Reflection Intensity in Children
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 ...

Determination of CTOD C in Fibre Metal Laminates by ASTM and Schwalbe Methods [PDF]
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.
