Overview

Due to their exceptional chemical and physical properties, fibre-reinforced polymer (FRP) composites 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. The heterogeneous and multi-scale nature of composite structures requires to understand their structural response at multiple scales including micro, meso and macro, as shown in Figure 1. The failure mechanisms at micro-level constituents including matrix, fibres and their interfaces lead to failure of macro-level structures. This multi-scale finite element method requires the solution of micro-level boundary value problem for each macro-level point of interest. Multi-scale finite element procedure provides accurate computational framework without any assumption of material models for the macro-level structure. On the micro-level, fibres, matrix and their interfaces are modelled explicitly with specialised material models. These material models capture the viscous behaviours of the resin and debonding of the fibre-matrix interfaces. Each micro-level problem involves the solution of nonlinear finite element problem with heterogeneous geometries, complex material models and dense meshes. Therefore, the associated computational cost is very high.

This project aims to developed 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 composite structures.
•The utilisation of reduced order models, including proper orthogonal decomposition (POD) and Empirical cubature method (ECM) to enhance the computational efficiency of the multi-scale finite element framework. The POD will reduce the number of degrees of freedom while the ECM will reduce the cost associated with numerical integration.
•Implementation of the developed reduced order multi-scale finite element analysis framework in open-source finite element software library MoFEM (Mesh-oriented finite element method).
•Optimisation of developed computational framework for the Queen’s University high-performance computing cluster, Kelvin.
•Simulation of structural mechanics problems subjected to static and impact loading to evaluate the effectiveness of the developed computational framework.
•Perform experiments on the same material system to validate results obtained from the finite element simulation.
This PhD project will be carried out within the Advanced Composites Research Group at Queen’s University Belfast consisting of academics, PhDs and post-doctoral researchers.

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 - biomemetics, 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.

As a result of the COVID-19 pandemic, we will be offering Academic English and Pre-sessional courses online only from June to September 2020.

  • Academic English: an intensive English language and study skills course for successful university study at degree level
  • Pre-sessional English: a short intensive academic English course for students starting a degree programme at Queen's University Belfast and who need to improve their English.
