Evaluation of low temperature toughness in welding of 420 MPa steel for arctic application
Key challenges in materials and welding for application of steel structures in arctic
Hydrogen embrittlement in structural steel welds – influence of varying the stress concentration
Hydrogen Embrittlement (HE) has been a known phenomenon for several decades. Despite that, it still represents a critical problem for Carbon Manganese steel used in structural applications. For the particular case of subsea pipelines and their weldments, atomic hydrogen from the cathodic protection ...
A geometric constraint independent hydrogen degradation law for high strength steels based on cohesive zone modeling
Cohesive zone simulation of grain size and misorientation effects on hydrogen embrittlement in nickel
H2 in the Norwegian Energy sector
From being mainly a source of damage to steel offshore structures and subsea pipelines, hydrogen is gradually becoming a candidate for energy storage. SINTEF and NTNU play a major role in both research fields....
HYDROGEN EMBRITTLEMENT IN FE3%SI, VISITED BY NANOMECHANICAL TESTING AND COHESIVE ZONE SIMULATION
This work is part of a multi scale computational and experimental approach in which first principle modelling, nanoscale experiments and continuum simulations are combined in order to represent hydrogen induced degradation and cracking. Nanomechanical testing in air and under electrochemical hydroge...
