Structural performance of steel pipe tee-junctions
(2014)
The behavior of steel pipe junctions (Tees) subjected to strong loading in the presence of internal pressure is examined in the present study. The analysis is based on a set of monotonic and cyclic out-of plane bending ...
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 ...
Structural integrity of steel hydrocarbon pipelines with local wall distortions
(2014)
Local distortions on pipeline wall in the form of dents or buckles may constitute a threat for the structural integrity of the steel pipeline. In the present paper, experimental research supported by numerical simulation ...
Numerical modelling of steel pipelines subjected to severe monotonic and cyclic straining
(2014)
Offshore and onshore pipelines may experience extreme loading conditions during their installation and operation, both of monotonic and cyclic nature. Loading actions such as pipeline lateral displacements, tensioning, or ...
Buckling of High-Strength Steel Cylinders Under Cyclic Bending in the Inelastic Range
(2014)
The present paper examines the structural behavior of elongated steel hollow cylinders, referred to as tubes or pipes, subjected to large cyclic bending, through a rigorous finite element simulation. The bent cylinders ...
Effects of UOE manufacturing process on pressurized bending response of offshore pipes
(2014)
Thick-walled steel pipes manufactured through the UOE process are used in deep-water pipeline applications for the safe and cost-effective transmission of hydrocarbon energy resources. Such pipes are subjected to bending ...
Finite element analysis of UOE pipes under external pressure and bending
(2014)
Thick-walled steel pipes manufactured through the UOE process are used in deep-water pipeline applications for the safe and cost-effective transmission of hydrocarbon energy resources. Such pipes are subjected to bending ...
Mechanics of Confined Thin-Walled Cylinders Subjected to External Pressure
(2014)
Motivated by practical engineering applications, the present paper examines the mechanical response of thin-walled cylinders surrounded by a rigid or deformable medium, subjected to uniform external pressure. Emphasis is ...
Seismic design of buried steel water pipelines
(2014)
The present paper provides an overview of available tools and provisions for the structural analysis and design of buried welded (continuous) steel water pipelines in seismic areas, subjected to earthquake action. Both ...
