... Abstract If not assessed properly, unstable crack growth in pipelines could result in detrimental leaks or ruptures. Fracture mechanics models are typically used to assess the susceptibility of pipelines to fail due to the presence of cracks or crack-like anomalies. To this end, an inelastic...

... Abstract Pipelines subject to ground deformations produced by geohazard loads carry high importance on pipeline analysis, design, and assessment due to risk of structural failure. An appropriate approach for evaluation is the finite element method (FEM), providing efficient and sophisticated...

...Abstract Abstract Pipeline seam welds are often inspected using ultrasonic In-Line Inspection (ILI) technologies. The measurement performance specification of an ultrasonic ILI tool is based on simple, planar, machined notches which are very reproducible, but are not representative...

...Abstract Abstract The pressure vessels are connected by pipelines to form a system. Thermal expansion of the pipeline imposes an additional load on the nozzle of the connected vessel. There are two methods to deal with the thermal expansion load of pipeline in the design of pressure vessel...

...Abstract Abstract Pipelines carrying oil and gas are susceptible to fatigue failure (i.e., unstable fatigue crack propagation) due to fluctuating loading such as varying internal pressure and other external loadings. Fatigue crack growth (FCG) prediction through full-scale pipe tests can...
