TL;DR: ABAQUS FE simulations of hydrogen diffusion in duplex stainless steel have been performed in this paper, where three models with different ferrite-austenite configurations have been applied and the hydrogen diffusion and hydrogen coefficient have been evaluated as a function of austenite phase size and shape and the calculated diffusion coefficients compared to literature.

TL;DR: In this article, a review of coupled diffusion and cohesive zone modelling is presented as a method for numerically assessing hydrogen embrittlement of a steel structure, and the model is able to reproduce single experimental results by appropriate fitting of the cohesive parameters, but there appears to be limitations in transferring these results to other hydrogen systems.

TL;DR: Coupled diffusion and cohesive zone modelling is presented as a method for numerically assessing HE of a steel structure while the model is able to reproduce single experimental results by appropriate fitting of the cohesive parameters, there appears to be limitations in transferring these results to other hydrogen systems.

TL;DR: In this article, a coupled finite element hydrogen diffusion and cohesive zone modelling approach was applied to simulate hydrogen induced fracture initiation in a hot-rolled bonded clad steel pipe, and the results were compared to experimental fracture mechanical testing in air and under in situ electrochemical hydrogen charging.

TL;DR: In this paper, the fracture properties of the interface between clad and base material of two 316L austenitic stainless steel pipes with and without Ni-interlayer were studied under in situ electrochemical hydrogen charging to establish crack growth resistance curves and fracture initiation toughness.
