Overview

Due to their exceptional chemical and physical properties, fibre-reinforced polymer (FRP) composite materials are used in a variety of engineering applications including aerospace, automotive, energy, marine, civil structures, and biomedical. During their service lives, composite structures are subjected to static and impact loading which ultimately lead to structural failure. Due to their heterogeneous nature, understanding their macro or structure level failure requires an understanding of a number of failure mechanisms on the micro level. Failure mechanisms at micro-level include fibres failure, matrix damage, and decohesion of fibre-matrix interfaces. Therefore, multi-scale modelling provides an accurate computational framework to simulate the behaviour of composite structures. Multi-scale finite element method requires the solution of micro-level problem for each macro-level point of interest. On the micro-level, fibres, matrix and their interfaces are modelled explicitly with specialised material models. Each micro-level problem involves the solution of nonlinear finite element problems with heterogeneous geometries, complex material models and dense meshes. Therefore, the associated computational cost is very high.

This project aims to develop and experimentally validate an efficient and accurate multi-scale finite element-based computational framework for the simulation of the structural performance of composite structures subjected to static and impact loading.
The objectives of this PhD project are outlined as follows:
•Development of multi-scale finite element analysis framework for fibre reinforced polymer composite structures.
•The utilisation of reduced order models to enhance the computational efficiency of the multi-scale finite element framework.
•Implementation of the developed reduced order multi-scale finite element analysis framework in open-source or commercial finite element software.
•Simulation of structural mechanics problems subjected to static and impact loading to evaluate the effectiveness of the developed computational framework.
•Use of Machine Learning and Artificial Neural Network (ANN) to improve computational efficiency.
•Perform experiments on the same material system to feed and validate results obtained from the finite element simulation.

Learning Outcomes

Course structure

You will carry out leading research under the guidance of your supervisory team. A full time student will normally complete in three years (up to a maximum of four), or part time over six years (up to a maximum of eight).

Research will usually be in one of the key, interlinked research themes in the School, and the subtopics they cover, include:-

Advanced Manufacturing and Processing - cost modelling, ergonomics, intelligent control, laser processing, life cycle analysis, material characterisation, mechatronics, parallel kinematic machines, polymer processing, robotics and ultra-precision manufacturing.

Future Aircraft - aero engines, aerodynamics, aeroelasticity, aircraft operations, design and analysis, optimisation and structural testing

Composite Materials and Structures -damage mechanics and crashworthiness, material characterisation, multifunctional composites and nano-enhanced composites

Simulation Technologies - FEA/CFD/EFG/DES/MD, kinematic modelling, meshing, multiscale/Multiphysics, optimisation, simulation intent, systems modelling, uncertainty quantification, virtual testing and design visual analytics and big data

Clean Energy - biofuels, catalysis, life cycle assessment, power systems, turbomachinery and waste management

Biomaterials and Biomechanics - biomimetics, material characterisation, mechanobiology and medical devices.

Also, over the course of study, you can attend postgraduate skills training organised by the Graduate School, or other internal and external training courses organised through your supervisor.

Entrance requirements

Graduate
The minimum academic requirement for admission to a research degree programme is normally an Upper Second Class Honours degree from a UK or ROI HE provider, or an equivalent qualification acceptable to the University. Further information can be obtained by contacting the School.

International Students

For information on international qualification equivalents, please check the specific information for your country.

English Language Requirements

Evidence of an IELTS* score of 6.0, with not less than 5.5 in any component (*taken within the last 2 years) is required.

International students wishing to apply to Queen's University Belfast (and for whom English is not their first language), must be able to demonstrate their proficiency in English in order to benefit fully from their course of study or research. Non-EEA nationals must also satisfy UK Visas and Immigration (UKVI) immigration requirements for English language for visa purposes.

For more information on English Language requirements for EEA and non-EEA nationals see: www.qub.ac.uk/EnglishLanguageReqs.

If you need to improve your English language skills before you enter this degree programme, INTO Queen's University Belfast offers a range of English language courses. These intensive and flexible courses are designed to improve your English ability for admission to this degree.

Aerospace Engineering costs

There are no specific additional course costs associated with this programme.

Additional course costs

All Students

Depending on the programme of study, there may also be other extra costs which are not covered by tuition fees, which students will need to consider when planning their studies . Students can borrow books and access online learning resources from any Queen's library. If students wish to purchase recommended texts, rather than borrow them from the University Library, prices per text can range from £30 to £100. Students should also budget between £30 to £100 per year for photocopying, memory sticks and printing charges. Students may wish to consider purchasing an electronic device; costs will vary depending on the specification of the model chosen. There are also additional charges for graduation ceremonies, and library fines. In undertaking a research project students may incur costs associated with transport and/or materials, and there will also be additional costs for printing and binding the thesis. There may also be individually tailored research project expenses and students should consult directly with the School for further information.

Bench fees

Some research programmes incur an additional annual charge on top of the tuition fees, often referred to as a bench fee. Bench fees are charged when a programme (or a specific project) incurs extra costs such as those involved with specialist laboratory or field work. If you are required to pay bench fees they will be detailed on your offer letter. If you have any questions about Bench Fees these should be raised with your School at the application stage. Please note that, if you are being funded you will need to ensure your sponsor is aware of and has agreed to fund these additional costs before accepting your place.
