Material degradation challenges at the interface between mechanics, chemistry and materials science are hindering the energy transition. Examples include the degradation of Li-Ion batteries, the embrittlement of metals exposed to hydrogen, and the early cracking of offshore wind turbines due to corrosion. New experimental insight, increasing computer power, multi-physics modelling paradigms and the development of techniques capable of handling evolving interfaces (e.g., phase field) have opened new horizons in the simulation and prediction of these technologically-relevant phenomena.
In this talk, the speaker will overview some of his team recent work in developing theoretical and computational models capable of predicting degradation phenomena in the areas of hydrogen embrittlement, Li-Ion batteries (conventional and all-solid-state) and metallic corrosion. Emphasis will be placed on the development of new electro-chemo-mechanical schemes that can explicitly simulate the underlying physical processes. Also, he will showcase how phase field methods enable predicting complex interfacial phenomena: from fracture mechanics to corrosion. The predictive capabilities of these formulations will be showcased by benchmarking against experimental data. Large-scale case studies of engineering interest will also be addressed to demonstrate the potential of phase field multi-physics modelling in enabling Virtual Testing in the energy sector.
