PhD Studentship - Modelling Crack Nucleation and Growth in Rail Steels

Supervisory Team: Professor Pedro Rivera and Dr Ben Cameron Project description: Rail safety is dependent upon the ability to control the Nucleation and Growth of cracks. Current popular techniques focus on crack prevention, e.g. through grinding, but the mechanisms leading to failure remain largely ununderstood. The topic has recently been reviewed here. Advanced modelling and characterisation techniques have never been systematically applied to predict and control crack formation and Growth in Rail. This project will combine dislocation theory, microstructure modelling and finite element analysis to predict Crack Nucleation and Growth inRail Steels. Modelling will be matched with advanced charactersiation. Both rolling contact fatigue and wear conditions will be studied.  We are looking for a candidate with a background in steel metallurgy and materials science. The ideal person for this position will have working knowledge of computational thermodynamics, being able to relate microstructure with properties, and use thermodynamic approaches to tailor microstructure. Knowledge of dislocation theory will be required, and the link of this with finite element modelling. Knowledge of computer programming is essential, combined with understanding of microstructural characterisation via electron microscopy and atom probe tomography. The project will be carried out in collaboration with the Rail Safety and Standards Board. The key output of this project is to provide a computational tool to predict crack formation for the complex environment and operation conditions of rail. If you wish to discuss any details of the project informally, please contact Professor Pedro Rivera, Engineering Materials Research Group, Email: p.rivera@soton.ac.uk Entry Requirements A very good undergraduate degree (at least a UK 2:1 honours degree, or its international equivalent). Closing date: 31 May 2024. Applications will be considered in the order that they are received, the position will be considered filled when a suitable candidate has been identified. Funding: We offer a range of funding opportunities for both UK and international students, including Bursaries and Scholarships.  For more information please visit PhD Scholarships | Doctoral College | University of Southampton  Funding will be awarded on a rolling basis, so apply early for the best opportunity to be considered.
