The project:
Engineering analysis methods that can predict and prevent the failure of safety-critical structures are fundamentally important to the energy industry. Nuclear reactors, wind turbines and oil platforms all need to be provably safe in the face of severe and complex loading scenarios. Recently, new structural integrity assessment methods based on Probabilistic Fracture Mechanics (PFM) have emerged in the nuclear energy industry. PFM allows engineers to understand the sources of risk to a structure better, and to predict more realistically what its response will be under uncertain loading conditions.
This project will focus on developing PFM-based methods so that they can be confidently used to assess a wider range of energy structures: particularly those where less restrictive risk profiles are acceptable. For example, in an offshore wind turbine, which is an un-crewed structure with a relatively short design life, a different risk profile is appropriate to that of a nuclear power reactor. You will investigate the limits of probabilistic structural integrity assessment and the interplay between assessment and measurement methods including Ultrasonic Non-Destructive Testing (UNDT) and residual stress measurement.
You will work at the National Structural Integrity Research Centre (NSIRC) in Cambridgeshire and the University of Bristol. The new probabilistic understanding of structural failure that you will develop will inform the UK standard BS 7910 and specialised nuclear-specific structural assessment codes, providing a safer and more rational underpinning for the next generation of energy infrastructure.

Applicants without a master's qualification may be considered on an exceptional basis, provided they hold a first-class undergraduate degree. Overseas applicants must satisfy the University of Bristol’s Profile E language category (www.bristol.ac.uk/study/language-requirements/profile-e/ ),
Basic skills and knowledge required
Essential: knowledge or experience of engineering stress analysis, and experience with statistical data analysis and/or scientific coding.
Desirable: Experience of engineering structural integrity or fitness-for-service assessment would be an advantage.
Funding:
£18,000 p.a. subject to confirmation and eligibility criteria for 3.5 years.
