For reliable hydrogen storage and distribution, we need to accurately predict the reliability of metallic components, especially their propensity to embrittlement with time. In this project, we will study hydrogen embrittlement in metallic alloys using advanced multiscale modelling techniques. 

The primary focus would be on understanding and predicting hydrogen diffusion and trapping behaviour at various length scales, ultimately leading to a more comprehensive understanding of the embrittlement process.

We will explore multiscale modelling frameworks employing atomistic simulations by employing Density Functional Theory (DFT) to model hydrogen interactions with individual atoms, vacancies, and dislocations at the atomic level. Following which we will perform mesoscale simulations and then bridge the scale with continuum scale simulations which can assess component-level response.

The project will contribute to the development of new hydrogen-resistant alloys for applications in pipelines, pressure vessels, and other critical infrastructure components exposed to hydrogen.

This PhD project offers an exciting opportunity to push the boundaries of multiscale modelling and contribute valuable knowledge to the critical field of hydrogen embrittlement in metals. By unravelling the complex interplay between hydrogen diffusion, trapping, and microstructure, the project can pave the way for safer and more reliable metallic components in a hydrogen-fuelled future.

Curriculum:

The models will be validated by comparing them with experimental data. There is a provision to perform exhaustive experiments as part of this project outcomes:

• A comprehensive multiscale modelling framework to predict hydrogen diffusion and trapping behaviour in metallic alloys.

• A deeper understanding of the mechanisms by which hydrogen interacts with various microstructural features, leading to embrittlement.

• Enhanced ability to predict the susceptibility of different metallic alloys to hydrogen embrittlement under varying service conditions.
