TITLE: Deciphering hydrogen-material interactions: a challenge across scales and disciplines
ABSTRACT:
Hydrogen embrittlement poses a major challenge to the safety and reliability of metallic
structures, as even small amounts of hydrogen can significantly reduce ductility, fracture toughness,
and fatigue resistance. Understanding and predicting hydrogen-metal interactions remains a critical
challenge, particularly for the development of hydrogen-based energy technologies. This talk will
present cross-disciplinary efforts to understand hydrogen-assisted failures through experiments and
multiscale modelling. The focus will be on the physical mechanisms governing hydrogen uptake,
diffusion, and crack initiation and propagation. These insights have enabled the development of
physically-based electro-chemo-mechanical models that accurately reproduce experimental
observations and predict material behaviour at engineering scales. Finally, recent advances in quantum
mechanically informed, thermo-chemo-mechanical crystal plasticity models will be discussed, with
particular emphasis on predicting hydrogen-material interactions under extreme temperatures relevant
to future hydrogen-powered aviation.

TITLE: Computational modelling of hydrogen embrittlement using a consistent multi-physics phase
field formulation
ABSTRACT:
When metals are exposed to electrolytes (such as water), surface reactions cause
hydrogen to be created, and subsequently absorbed into the metal. This, in turn, then reduces the
toughness of the metal, creating the potential for premature failure. One of the main challenges with
predicting this failure is the large differences in environments that occur in and around the failure
region: Corrosion aims to lower the pH while hydrogen absorption raises it, while the limited crack
opening at the onset of damage limits diffusion of ions into and out of the crack, resulting in strong
electric potential gradients. Here, we present a novel phase-field model that explicitly couples the
diffusive processes to the crack opening, obtaining a consistent formulation for the electrochemical
processes within the fracture. The talk will discuss the mathematical basis of this formulation and
present representative benchmark cases showing the impact of correctly capturing these effects for static and propagating fractures.
