Virtual failure assessment diagrams for hydrogen transmission pipelines
J. Wijnen, J. Parker, M. Gagliano +1
We combine state-of-the-art thermo-metallurgical welding process modelling with coupled diffusion-elastic-plastic phase field fracture simulations to predict the failure states of…

A computational framework to predict weld integrity and microstructural heterogeneity: application to hydrogen transmission
J. Wijnen, J. Parker, M. Gagliano +1
We present a novel computational framework to assess the structural integrity of welds. In the first stage of the simulation framework, local fractions of microstructural constitue…
