About This PhD Project

Project Description

Project: CRITICAL PROCESSING FACTORS THAT AFFECT THE STRENGTH OF JOINTS WHEN JOINING SIMILAR AND DISSIMILAR SUBSTRATE MATERIALS USED FOR PRESSURE VESSELS AND PIPING SYSTEMS OPERATING IN EXCESS OF 500 BAR

Congratulations on taking your first steps toward a Research Degree with Coventry’s Faculty of Engineering, Environment and Computing. As an ambitious and innovative University, we’re investing an initial £100m into our new research strategy, ‘Excellence with Impact’. Through original approaches from world-leading experts, we’re aiming for our research to make a tangible difference to the way we live. As a research student you are an integral part of Coventry’s lively and diverse research community and contribute to our reputation for excellence. With our exceptional facilities and superb support mechanisms you are afforded every opportunity for academic success.

Duration: 3 years Fixed Term

The Project


The use of high pressure/high-integrity conduits for transferring pressurised fluids in the transportation sector is increasing. The specific transportation application that will be the basis of this study will be pressurised fuel rails. Joining strategies for sub-components of pressurised automotive piping and delivery systems have typically been designed for low-moderate fluid pressures (up to 250bar).

Through investigating new brazing alloy chemistries, joint design and gaps, substrate thickness and interface properties, along with thermal delivery systems, this study will develop and enhance our understanding of high-temperature fluid flow, defect formation characteristics, optimum application type and ultimately our manufacturing capability.

The output data will lead us to developing appropriate models of joint design for a filler material type, joint configuration and process that determine the sensitivity of those essential variables defined within industrial codes, leading to enhanced mechanical integrity/durability.

About the Centre/Department


The Institute for Advanced Manufacturing and Engineering (AME) is a £32m+ collaboration between Coventry University and Unipart Manufacturing. This project is supported by the Higher Education Funding Council for England’s Catalyst Fund.

AME is building a bespoke ‘Faculty on the Factory Floor’ at Unipart Powertrain Application’s site in the heart of Coventry.

This forms the focal point of activity and has state-of-the-art robotic automation, forming, joining, analysis and simulation, metrology and product verification technology.

Successful Applicants


- A (2:1 or above) BSc or MEng/MSc in Mechanical Engineering or a related field, such as Materials Engineering.
- Ability to undertake stress analysis analytically.
- Demonstrated experience in using finite element modelling.
- Basic understanding of mechanical testing/mechanical behaviour of polycrystalline metallic materials.
- Able to use own initiative and creativity to solve problems and meet deadlines.
- Developed interpersonal skills to work effectively with a wide range of people, including staff and students at all levels, and as part of a team.

Additionally:
- It is expected that the applicant will have demonstrated experience with analytical stress analysis, finite element modelling, as well as some knowledge about mechanical testing and interpretation of mechanical behaviour of polycrystalline metallic materials
