This project is one of a number that are in competition for funding from the University of Bath URSA competition , for entry in September 2025.

Early application is encouraged, as excellent candidates may receive an early offer of a funded place before the end of the year. To be eligible for early consideration, you must apply before 24 November 2024.

Project Background:

The physical resilience of vulnerable buildings and critical infrastructure against malevolent attacks is of growing concern, in both developed and emerging economies. Practical and cost-effective means of protecting concrete structures is therefore of interest, both for new-build projects, and for retrofitting in response to evolving threats.

Past research has examined elastomer coating as a low-cost protective solution for concrete. Such coatings offer enhanced protection in certain dynamic load regimes e.g. local impact and severe blast, but not in others e.g. during fluid-structure interaction and during dynamic flexure. Recent research at the University of Bath has demonstrated the potential for a novel type of protective coating: a shear-stiffening gel (SSG). SSG coatings have been developed for protection of composite panels, reducing the extent of internal damage by 70% compared with uncoated panels and by 55% compared with traditional elastomer coatings. The additional improvement in impact resistance is the result of the shear-stiffening response of the gel which enables an additional energy-absorption mechanism via a viscous-rubbery phase transition.

This PhD will seek to develop design guidelines for effective implementation of SSG as a protective solution for concrete structures in response to blast and impact load events. An experimental campaign will interrogate the protective performance of the gel across a range of strain rates and will include quasistatic compression tests, low and high velocity impact tests and damping analysis. The experimental programme will be supplemented by finite element analysis. This will be used to understand the protective mechanisms at play with a view to developing design guidelines to achieve an optimal protective effect.

Candidate requirements:

Applicants must have, or be about to obtain, a UK Honours degree 1 ^st or 2.1, or international equivalent.

Non-UK applicants, who are not currently studying in the UK, must meet the programme’s English language requirement before the application deadline – no exceptions will be considered.

Application Instructions

Please follow the below instructions carefully.

You must make a formal application via the University of Bath’s online application form for a PhD in Mechanical Engineering

Please note that you can apply for a maximum of two PhD projects on this programme.

In the ‘Funding Your Studies’ section, you must select ‘University of Bath URSA’ from one of the drop-down menus.

In the ‘Your PhD project’ section, you must quote the project title in the PhD project title field, and you must quote the lead supervisor’s name in the field ‘Name of intended supervisor at University of Bath.’

If you are applying for two projects, you must quote the project title for your second choice project in the field ‘Project 2 Title’ and the lead supervisor’s name in ‘Name of intended supervisor for 2 ^nd choice project at University of Bath.

You must ensure that you follow the above steps correctly. Failure to complete these steps will cause errors in the automated processing of your application and may mean that you are not considered for a particular project.
