Key Information
Swansea University’s College of Engineering, in association with the National Research Network in Advanced Engineering and Materials (AEM), invites applications for a fully-funded PhD studentship.
This exciting new PhD opportunity combines fundamental materials science, thermo-mechanical characterisation, design via numerical modelling and additive manufacture (or 3D printing) of complex geometrical structures.
The aim of the project is to design new smart components for high precision structural casings for lenses, where accurate dimensional tolerances over a range of temperatures are paramount. These products require multiple functionalities. They must be lightweight, stiff and robust. Most critically, they also need to have tailored coefficients of thermal expansion (CTE), perhaps negative CTEs (multi-materials) and/or negative Poisson’s ratios using auxetic lattices. Furthermore, these properties may need to be graded throughout the component structure.
This project addresses a real industrial challenge and exploits existing facilities and expertise within the College of Engineering at Swansea such as:
- new materials characterisation facilities (MACH1 labs)
- modern Additive Manufacturing capabilities
- numerical modelling expertise
The successful candidate will be working as part of an industrial-academic collaboration team with Qioptiq (http://www.qioptiq.com), implementing early product design cycles. As a designer and manufacturer of photonic products and solutions, Qioptiq serve a wide range of markets and applications in the areas of medical and life sciences, industrial manufacturing, defence, aerospace, research and development.
This collaboration will involve:
- Preliminary selection of materials, designs, and thermo-physical data.
- More advanced design of components incorporating lattice structures, FE simulation of performances and optimisation of design prior to manufacture.
- Mechanically testing actual manufacturing components by Additive Manufacturing and metallurgical quality evaluation – some of the materials will have to be qualified for use by AM.
- Conducting post-manufacturing steps & testing of prototype components.
In order to complete this work you will learn how to:
- Use thermo-physical measurement equipment (laser flash analysis, differential calorimetry, dilatometry, etc.)
- Use a powder-bed additive manufacturing machine with a combination of different materials (Ti-6Al-4V, INVAR, Aluminium alloys, etc.)
- Write and/or use Finite Element Stress analysis and CAD software
Eligibility
Candidates should have a first class or upper second class honours degree in engineering, mathematics and/or science.
Work conducted by the successful candidate will comprise of an equal part of theory & computation, experimentation and pragmatic engineering. It is essential that the candidate will have covered the following areas at undergraduate level:
- Heat transfer
- Thermal-structural properties of materials
- Computer Aided Design
It is preferable that the candidate would also have a good understanding of:
- Numerical programming and computational geometry
- Experimental heat transfer
- Finite Element Analysis
- Manufacturing methods
These scholarships are open to UK/EU and international students, but please note that only the UK/EU fee level will be covered. International students will be expected to pay the difference between UK/EU fees and international fees.
Funding
The studentship covers the full cost of UK/EU tuition fees, plus a tax free stipend of £14,562 p.a.
There will also be additional funds available for research expenses and conference attendance.
Location: Swansea, UK
Applications close on Friday 24 July 2015.
