Abstract: The winding and unwinding of a pipeline in the reeling installation process involve repeated excursions into the plastic range of the material, which induce ovality, elongation, and changes to the mechanical properties. ...

Abstract: In our recent work on reeling of a pipeline onto a large-diameter rigid reel, we noticed a small error in the calculation of the moment acting on a section of pipe that is in contact with the rotating reel reported in the ...

Abstract: Abstract. It is well recognized that girth welds of carbon steel pipe lined with a thin layer of a corrosion-resistant alloy constitute a weakness. Plastic bending to levels such as those imposed by reel-lay installation ...

Abstract: Part II presents two modeling schemes for simulating the reeling/unreeling of a pipeline, with the aim of establishing the degrading effect of the process on the structural performance of the pipeline. A three-dimensional ...

Abstract: The shear stress–strain response of an aluminum alloy is measured to a shear strain of the order of one using a pure torsion experiment on a thin-walled tube. The material exhibits plastic anisotropy that is established ...

Abstract: The inelastic response and failure of Al-6061-T6 tubes under combined internal pressure and tension is investigated as part of a broader study of ductile failure of Al-alloys. A custom experimental setup is used to load ...
