Ground movements caused by continuous freezing and thawing of the ground in arctic
regions can potentially lead to pipeline failures. There are many factors such as internal …

A circumferential crack in the fusion line is a major threat to the structural integrity of the
pipeline girth weld because it may possibly lead to fracture failure when subjected to large …

Pipelines subjected to displacement-controlled loading such as ground movement may
experience significant longitudinal strain. This can potentially impact pipeline structural …

Cracks and corrosion in pipelines can occur simultaneously, representing a hybrid defect
known as cracks in corrosion (CIC), which is often difficult to model using the available …

The single edge notched tension (SENT) test is commonly used to evaluate the less-
conservative fracture toughness of pipeline steels. The R-curve (crack tip opening …

Pipelines exposed to geo-hazards such as moving slopes, discontinuous permafrost, and
other ground movements may be subjected to displacement-controlled loading, which may …

Pipelines can be exposed to a wide variety of loads, depending on the environments and
the area of application. These loads may impose large longitudinal plastic strain on …

Reliability assessment on fracture failure of pipes due to corrosion has recently stimulated
great interest in academia. However, a review of the literature suggests that little research …

Based on the JA two-parameter characterization, this paper presents a systematic study of
the crack-tip constraint for clamped single-edge notched tension (SET) specimens …

Understanding the fracture behavior of pipeline steel is crucial for ensuring the integrity of
pipelines in the energy transportation industry. This comprehensive thesis investigates the …
