Abstract: This study presents a detailed assessment for the response of elbow elements in ABAQUS under internal pressure. Two main cases are considered: (1) a standalone 90 deg pipe bend, which was analyzed using both elastic and ...

Abstract: This study investigates the fracture behavior of single-edge notched tension (SENT) specimens made from API X52 vintage pipeline steel by comparing the extended finite element method (XFEM) and the traditional finite element ...

Abstract: AbstractPrompt detection and management of imperfections, such as cracks or crack-like anomalies, in onshore and offshore oil and gas pipelines remain major challenges in pipeline maintenance. Accurate evaluation of failure ...

Abstract: Abstract. The extended finite element method (XFEM) has recently emerged as a highly effective tool for analyzing crack propagation in complex structures, but its use in pipeline fracture studies, particularly with cohesive ...

Abstract: AbstractThe CorLAS model is widely used in the pipeline industry for predicting the failure pressure of pipelines with axial surface cracks, primarily due to its low computational and moderate prediction accuracy compared ...

Abstract: 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 pipelines, which could constitute a significant ...
