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…

Computational predictions of weld structural integrity in hydrogen transport pipelines
T. K. Mandal, J. Parker, M. Gagliano +1
We combine welding process modelling with deformation-diffusion-fracture (embrittlement) simulations to predict failures in hydrogen transport pipelines. The focus is on the struct…
