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 …

Pipelines have become a popular method of energy transportation for natural gas and oil
due to their high reliability and efficiency. However, geohazards pose a significant threat to …

Carbon fiber-reinforced polymer (CFRP)-retrofitted steel beams are likely exposed to
significant service temperature variations due to seasonal and daily temperature changes …

Anomalies as misalignment, microcrack are inevitable for large diameter high strength steel
pipelines. To ensure the strain capacity of mismatched welding joint with misalignments of D …

There is increasing attention on the fracture of pipelines with girth weld, as a result of the
accidents caused by additional loads occurring occasionally. However, there is little …

Strain-based design (SBD) plays an important role in pipeline design and assessment of
pipelines subjected to geo-hazards. Under such hazards, a pipe can be subjected to …

The failure accidents in girth weld of pipelines occur frequently due to the combination of
internal defects and external loads. However, the research on the fracture behavior of girth …

This study compares the capabilities of eXtended Finite Element Method (XFEM) against the
traditional Finite Element Method (FEM) in predicting the fracture behavior of Single Edge …

Ground movement events pose a significant threat to buried natural gas and oil pipelines
which resulted in an estimated $388 million in damages from 2002 to 2022. Strain-based …

This thesis examines the Tensile Strain Capacities (TSCs) of API 5L steel pipelines, focusing
on X70 and X100 grades. It evaluates X70 base metal pipelines with internal or external …
