A coupled diffusion and cohesive zone modelling approach for numerically assessing hydrogen embrittlement of steel structures
Jemblie, Lise; Olden, Vigdis; Akselsen, Odd Magne (Journal article; Peer reviewed, 2017)Simulation of hydrogen embrittlement requires a coupled approach; on one side, the models describing hydrogen transport must account for local mechanical fields, while on the other side, the effect of hydrogen on the ... -
A review of cohesive zone modelling as an approach for numerically assessing hydrogen embrittlement of steel structures.
Jemblie, Lise; Olden, Vigdis; Akselsen, Odd Magne (Journal article, 2017)Simulation of hydrogen embrittlement requires a coupled approach; on one side, the models describing hydrogen transport must account for local mechanical fields, while on the other side, the effect of hydrogen on the ... -
Cohesive zone modelling of hydrogen induced cracking on the interface of clad steel pipes
Jemblie, Lise; Olden, Vigdis; Maincon, Philippe Emmanuel; Akselsen, Odd Magne (Journal article; Peer reviewed, 2017)A coupled finite element hydrogen diffusion and cohesive zone modelling approach has been applied to simulate hydrogen induced fracture initiation in a hot rolled bonded clad steel pipe. The results are compared to ... -
Fracture toughness and hydrogen embrittlement susceptibility on the interface of clad steel pipes with and without a Ni-interlayer
Jemblie, Lise; Bjaaland, Helena; Nyhus, Bård; Olden, Vigdis; Akselsen, Odd Magne (Journal article, 2017)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 ... -
Hydrogen embrittlement of clad steel pipes: Experiments and FE modelling
Jemblie, Lise (Doctoral theses at NTNU;2018:200, Doctoral thesis, 2018)Pipes with an inner layer of corrosion resistant alloy, so called clad pipes, are increasingly used in the oil and gas industry as en economical viable option for corrosion management, combining the mechanical properties ... -
Modeling of Hydrogen Diffusion in 25% Cr Super Duplex Stainless Steel
Jemblie, Lise (Master thesis, 2012)Over the last years, several failures in duplex and super duplex stainless steel structures in subsea applications are reported to be a result of hydrogen induced stress cracking. One main source of hydrogen is found to ... -
Safe pipelines for hydrogen transport
Jemblie, Lise; Hagen, Anette Brocks; Hagen, Catalina Hoem Musinoi; Nyhus, Bård; Alvaro, Antonio; Wang, Dong; Koren, Erik Aas; Johnsen, Roy; Zhang, Zhiliang; Yamabe, Junichiro; Matsunaga, Hisao; Olden, Vigdis (Journal article; Peer reviewed, 2024)The hydrogen compatibility of two X65 pipeline steels for transport of hydrogen gas is investigated through microstructural characterization, hydrogen permeation measurements and fracture mechanical testing. The investigated ...
