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 ... -
Bending deformation capacity of large-diameter spiral-welded tubes
(2014)Numerical simulations are conducted to define the bending deformation capacity of large-diameter spiral-welded tubes, towards efficient strain-based design. Under bending loading, the principal failure mode of those tubes ... -
Bending response of lap welded steel pipeline joints
(2020)The paper presents a combined experimental and numerical investigation of the bending response of lap welded joints in pressurized steel water pipelines. It is motivated by the structural performance of large-diameter steel ... -
Buckling behaviour of thin-walled cold formed steel platforms subjected to bending
(2008)The paper studies the behaviour of thin walled cold formed steel beams in bending, through nonlinear finite element analysis. These types of beams are usually used as platforms in scaffold configurations. The research aims ... -
Buckling of internally-pressurized spiral-welded steel pipes under bending
(2018)The mechanical behavior of spiral-welded large-diameter steel pipes is simulated, with the purpose of defining their bending deformation capacity against local buckling. The steel pipes are candidates for hydrocarbon onshore ... -
Experimental and numerical investigation of the bending capacity of spiral-welded steel tubes
(2016)To investigate the structural behaviour of large-diameter spiral-welded steel tubes under bending, a full scale experimental program has been performed, consisting of thirteen 42-inch diameter, spiral-welded steel tubes ... -
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”) ... -
A mathematical method for the determination of the critical axial loads of continuous beams with unilateral constraints for various initial geometric imperfections
(2013)This paper deals with the calculation of the axial critical loads of continuous beams with unilateral constraints. The paper emphasizes in the determination of the instability loads of continuous beams with initial geometric ... -
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. ...
