Accurate modeling of the cyclic response of structural components constructed of steel with yield plateau
(2012)A time-independent constitutive model for structural steels with a yield plateau is presented. The model is based on the basic principles of time-independent plasticity. The model couples the nonlinear kinematic hardening ... -
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 ... -
Buckling and classification of high-strength steel CHS tubular members under axial compression and bending
(2012)EN 1993-1-1 provisions classify high-strength steel CHS members with relatively low values of D/t ratio as Class 3 or 4, so that their strength is based on elastic behavior only, neglecting their capability of sustaining ... -
Buckling capacity of radially compressed thin-walled reinforced cementitious spheres
(2018)High performance cementitious materials have made possible the construction of slender thin cementitious shells. For their design, the most relevant recommendations are those provided by the International Association of ... -
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 clad pipes under bending and external pressure
(2011)The present paper concerns the structural behaviour of clad pipes. This is a double wall pipe, composed by two pipes that are in contact through an appropriate manufacturing procedure; a thick-walled carbon steel "outer ... -
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 ... -
Buckling of unconfined and confined thin-walled steel cylinders under external pressure
(2008)The present paper investigates the structural stability of thin-walled steel cylinders subjected to uniform external pressure. A brief discussion of unconfined steel cylinder buckling is presented first. Subsequently, ... -
Buried steel pipelines crossing strike-slip faults
(2012)The paper examines the behaviour of buried steel pipelines crossing active strike-slip faults. The vertical fault plane is crossed by the pipeline at an angle ranging between zero and 45 degrees, causing significant plastic ... -
Compression-only behavior: Effect of prestress and shell rheology on bifurcation diagrams and parametric stability of coated microbubbles in an unbounded flow
(2022)Lipid-shelled microbubbles exhibit a strain-softening behavior and thus are characterized by preferential excursion from equilibrium during expansion at insonation. However, experimental studies have reported a counterintuitive ... -
Differences in required structural efficiency of standard commercial steel greenhouses among EU countries: A hellenic experience
(2012)Since the climate and seismic conditions vary significantly among European countries (and sometimes even in different areas of the same country) the European Standard for the design and construction of greenhouses for ... -
Dynamic simulation of a coated microbubble in an unbounded flow: Response to a step change in pressure
(2017)A numerical method is developed to study the dynamic behaviour of an encapsulated bubble when the viscous forces of the surrounding liquid are accounted for. The continuity and Navier-Stokes equations are solved for the ... -
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 ... -
Failure analysis of a welded steel pipe at Kullar fault crossing
(2017)The seismic response of a 2200-mm-diameter welded steel pipe at strike slip Kullar fault crossing in Izmit, Kocaeli during 1999 Kocaeli earthquake is investigated. The pipe was crossing the fault-line with an angle of 55° ... -
Failure modes and buckling capacity of thin cylindrical reinforced cementitious shells under axial compression
(2018)High performance cementitious composites have made possible the manufacturing of thin cementitious shell structures which are prone to buckling. Perhaps the most comprehensive design procedure for such shells is provided ... -
Failure of locally buckled pipelines
(2006)Mechanical damage in steel pipelines in the form of local buckles due to excessive bending deformation, may severely threaten their structural integrity. The present paper describes experimental and numerical research ... -
Fatigue failure of buckled pipelines
(2004)Quite often, steel buried pipelines exhibit local buckles due to imposed deformations, which may cause failure because of fatigue from repeated loading. When such buckles are detected in a steel pipeline, a decision must ... -
Finite element analysis of buried steel pipelines under strike-slip fault displacements
(2011)The present paper investigates the mechanical behavior of buried steel pipelines, crossing active strike-slip tectonic faults. The fault plane is vertical and crosses the pipeline axis at a certain angle. The interacting ...
