Research Associate in Hydrogen Embrittlement Modelling

Applications are encouraged for a Research Associate position to work on the prediction of hydrogen-assisted failures using computational methods, on the project titled “Simulation-based assessment of the interplay between hydrogen, defects and plastic straining,” funded by Shell. This role will work under the supervision of Dr Emilio Martínez-Pañeda and be based in the Mechanics of Infrastructure Materials research group.

Hydrogen embrittlement is arguably the biggest threat to the deployment of a hydrogen energy infrastructure and the cause of numerous structural integrity problems in the transport, defence, marine and construction sectors. When exposed to hydrogen, metallic materials exhibit a significant drop in ductility and fracture toughness (of up to 90%). Building upon recent developments in multi-physics modelling and computational fracture mechanics (e.g., phase field), there is an opportunity now to deliver predictions over technologically-relevant scales and map safe regimes of operation.

You will have access to HPC facilities and codes. The initial term will be one year.

Duties and responsibilities

This role will be responsible for conducting finite element analyses to predict the failure of materials and components due to hydrogen assisted cracking. You will be required to have (or develop) a sound understanding of fracture mechanics and combine sophisticated calculations with first-order insight from sound analytical methods. The work will involve use of COMSOL or ABAQUS but it will also be possible to utilise in-house or open-source codes. You will be expected to address both fundamental and applied problems, and to take part in collaborative work including the activities of the research group, as well as to submit publications to reputed journals and liaise with academic collaborators and sponsors.

Essential requirements

• PhD in engineering, mathematics, physics, materials science, or other closely-related fields


• Experience in numerical analysis


• Ability to carry out finite element analysis


• Ability to conduct a detailed review of recent literature


• Willingness to work as part of a team and to be open-minded and cooperative

Further information

This is a full time, fixed term position for 12 months and based at South Kensington Campus.
