Viscous regularization for cohesive zone modelling under constant displacement: an application to hydrogen embrittlement simulation

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1376522

The convergence problem during the cohesive zone modelling of hydrogen embrittlement in constant displacement scenario is attributed to the numerical instability which is studied analytically in the present work. The property of numerical stability is directly associated with the number of solutions...

Hydrogen Embrittlement at the Interface of Clad Steel Pipes – Fracture Mechanical Testing and FE Simulations

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1397243

The presence of a Ni-interlayer between clad and pipeline steel was found to reduced the fracture initiation toughness with 44 % for testing in air, while it raised the fracture initiation toughness with 216 % for testing under CP. • Fracture mechanical testing of the weld heat-affected zone clad in...

The effect of low temperatures on the fatigue crack growth of S460 structural steel

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1307955

The Fatigue Ductile–Brittle Transition (FDBT) is a phenomenon similar to the fracture ductile to brittle transition, in which the fracture mode of the fatigue cracks changes from ductile transgranular to cleavage and/or grain boundary separation. Fatigue at temperatures below the FDBT has a much dif...

A uniform hydrogen degradation law for high strength steels

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1344104

The degrading effect of hydrogen on high strength steels is well recognized. The hydrogen degradation is dependent not only on hydrogen content, but also on geometric constraints or equivalently, level of stress triaxiality, which means the hydrogen degradation locus is not likely to be a unique mat...

Properties in submerged arc welding of X80 plate for Arctic applications

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1280114

Pipelines for transport of oil and gas in Arctic areas are subjected to some extreme challenges; among these being low temperatures. Thus, the steel behaviour with respect to the ductile to brittle transition will be important. Moreover, when the design temperature falls down to -50 to -60°C, the to...

Fatigue properties of a 420 MPa structural steel at low temperature

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1280116

The exploration of oil and gas fields in the arctic brings several challenges in the use of structural steels concerning their low-temperature properties. Among others, fatigue behavior needs also to be considered for arctic applications, despite little attention to fatigue at low temperature has be...
