\nTITLE:<\/strong> Deciphering hydrogen-material interactions: a challenge across scales and disciplines<\/p>\n
\nstructures, as even small amounts of hydrogen can significantly reduce ductility, fracture toughness,
\nand fatigue resistance. Understanding and predicting hydrogen-metal interactions remains a critical
\nchallenge, particularly for the development of hydrogen-based energy technologies. This talk will
\npresent cross-disciplinary efforts to understand hydrogen-assisted failures through experiments and
\nmultiscale modelling. The focus will be on the physical mechanisms governing hydrogen uptake,
\ndiffusion, and crack initiation and propagation. These insights have enabled the development of
\nphysically-based electro-chemo-mechanical models that accurately reproduce experimental
\nobservations and predict material behaviour at engineering scales. Finally, recent advances in quantum
\nmechanically informed, thermo-chemo-mechanical crystal plasticity models will be discussed, with
\nparticular emphasis on predicting hydrogen-material interactions under extreme temperatures relevant
\nto future hydrogen-powered aviation.<\/p>\n

\nhydrogen to be created, and subsequently absorbed into the metal. This, in turn, then reduces the
\ntoughness of the metal, creating the potential for premature failure. One of the main challenges with
\npredicting this failure is the large differences in environments that occur in and around the failure
\nregion: Corrosion aims to lower the pH while hydrogen absorption raises it, while the limited crack
\nopening at the onset of damage limits diffusion of ions into and out of the crack, resulting in strong
\nelectric potential gradients. Here, we present a novel phase-field model that explicitly couples the
\ndiffusive processes to the crack opening, obtaining a consistent formulation for the electrochemical
\nprocesses within the fracture. The talk will discuss the mathematical basis of this formulation and
\npresent representative benchmark cases showing the impact of correctly capturing these effects for static and propagating fractures.<\/p>\n","protected":false},"excerpt":{"rendered":"
