| Abstract Scope |
Predicting hydrogen embrittlement and stress corrosion cracking is of increasing importance due to ageing infrastructure and the promise that hydrogen holds as future energy carrier. In this talk, I will show how computational approaches based on the finite element method can be used to predict hydrogen assisted fractures and localised corrosion. Multi-physics models and phase field approaches are combined to track the evolution of cracks and the corrosion front. The mechanisms driving hydrogen embrittlement and corrosion damage will be discussed. The potential of mechanistic computational models will be demonstrated by benchmarking against laboratory experiments. Moreover, the capabilities of the modelling framework presented in enabling Virtual Testing will be showcased; from predicting the failure of bolts to the progressive failure of pipelines. The talk will conclude by discussing recent extensions to capture hydrogen assisted fatigue. |
