Bending and buckling of internally-pressurized steel lined pipes
(2019)During offshore installation, steel lined pipes are subjected to severe plastic bending, resulting in detachment of the thin-walled liner pipe from the outer pipe and eventually, the formation of local buckling in the form ... -
Buckling design of confined steel cylinders under external pressure
(2010)Thin-walled steel cylinders surrounded by an elastic medium, when subjected to uniform external pressure may buckle. In the present paper, using a two dimensional model with nonlinear finite elements, which accounts for ... -
Buckling of thin-walled long steel cylinders under bending
(2010)The present paper investigates structural response and buckling of long unstiffened thin-walled cylindrical steel shells, subjected to bending moments, with particular emphasis on their stability design. The cylinder ... -
Effect of Manufacturing Process on Lined Pipe Bending Response
(2020)The effects of manufacturing process on mechanically lined pipe structural performance are investigated. Alternative manufacturing processes are considered, associated with either purely hydraulic or thermo-hydraulic ... -
Elephant's foot buckling and imperfection sensitivity of internally pressurized thin-walled metal cylinders subjected to bending
(2016)Upright cylindrical steel storage tanks, subjected to lateral loading, may fail in the form of local buckling near their bottom, due to the simultaneous action of excessive axial compression in the presence of internal ... -
Influence of lined pipe fabrication on liner wrinkling
(2019)An economical method to protect offshore pipelines against corrosive ingredients of hydrocarbons is a double-walled (also called “lined” or “bi-metallic”) pipe, in which a thick-walled low-alloy carbon steel (“outer pipe”) ... -
Stability of long transversely-isotropic elastic cylindrical shells under bending
(2010)The present paper investigates buckling of cylindrical shells of transversely-isotropic elastic material subjected to bending, considering the nonlinear prebuckling ovalized configuration. A large-strain hypoelastic model ... -
Structural response of steel lined pipes under cyclic bending
(2022)Motivated by reeling installation of mechanically-lined offshore steel pipes, the present paper investigates the structural performance of a bi-material lined pipe under cyclic bending, using advanced finite element tools. ... -
Ultimate bending capacity of spiral-welded steel tubes - Part II: Predictions
(2016)In the second part of this investigation, numerical simulations are conducted using nonlinear finite element simulations, to define the bending strength and deformation capacity of large-diameter spiral-welded steel tubes. ...
