R-curve evaluation of pipeline girth welds using advanced measurement techniques [PDF]
A strain-based flaw assessment procedure is recommended for girth welded pipelines subjected to large deformations. To evaluate the allowable defect dimensions, the tearing resistance needs to be characterized.

Sensitivity study of crack driving force predictions in heterogeneous welds using Vickers hardness maps [PDF]
Weld flaws often require an engineering critical assessment (ECA) to judge on the necessity for weld repair. ECA is a fracture mechanics based prediction of the integrity of welds under operating conditions.

Study of SENT specimens with a tilted notch to evaluate ductile tearing in spiral welded pipeline applications [PDF]
There is an increasing interest for the use of spiral welded pipelines in strain based design applications. Environmentally imposed loads are able to plastically deform the pipelines, meaning that their structural response is of the utmost importance ...

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.

A numerical analysis of the relation between CTOD and fatigue crack growth [PDF]
El cálculo de la vida a fatiga durante la etapa de propagación de la grieta se suele realizar relacionando da/dN con ΔK. Sin embargo, la influencia que en estos análisis tiene el parámetro ΔK debe recaer en algún otro parámetro no lineal cercano al ...

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 ...

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.

Strain capacity of girth welded joints in HSAW pipes [PDF]
The general aim of a recently finalized European project, i.e. EU RFCS SBD-Spipe, is to generate specific know-how concerning the development and possible use of spirally welded pipes for demanding applications.
