Hydrogen embrittlement susceptibility of clad steel pipes
Cohesive zone modelling of hydrogen induced cracking on the interface of clad steel pipes
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
A review of cohesive zone modelling as an approach for numerically assessing hydrogen embrittlement of steel structures.
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....
A coupled diffusion and cohesive zone modelling approach for numerically assessing hydrogen embrittlement of steel structures
Fracture toughness and hydrogen embrittlement susceptibility on the interface of clad steel pipes with and without a Ni-interlayer.
The objective of the present work has been to study the fracture properties of the interface between clad and base material of two 316 L austenitic stainless steel - X60/X65 carbon steel hot roll bonded clad pipes; with and without a Ni-interlayer. Fracture mechanical tests were performed in air and...
