PhD: Wave propagation and Αcoustics of Periodic Composite and Hybrid Structures and Optimisation
Supervisors: Dr Dimitrios Chronopoulos, Prof Seamus Garvey and Prof Shuguang Li
My research is on Acoustics and Wave Propagation and Vibration of Composite and Hybrid Materials. The focus is aimed at the periodic structures, and more specifically at the band gaps (frequencies where any vibration is annihilated) that these structures exhibit. Furthermore, optimisation methods are examined and developed to achieve the best solutions of periodic structures, concerning structural characteristics and banded behaviour. Experimental validation in vibration experimental setup is, also, conducted.
PhD: Wave propagation and nonlinear interaction phenomenon in periodic composite structures
Supervisors: Dr Dimitrios Chronopoulos, Dr Savvas Triantafyllou and Dr Gregor Tanner
The extensive usage of composite materials in modern industrial applications implies a great range of possible structural failure modes for which the structure has to be frequently and thoroughly inspected. Linear ultrasonic guided wave techniques have been widely employed for this purpose. The techniques are primarily sensitive to gross defects but much less sensitive to micro localised damage, which is more common in composite structures. This research is therefore aimed at developing efficient and versatile computational models for elastic wave propagation characteristics, and interaction phenomenon of the wave with linear or/and nonlinear structural damage or discontinuities.
PhD: Space Launcher Validation and Verification using IQCs
Supervisors: Dr Harald Pfifer and Prof Atanas Popov
The objective of this PhD is to provide new tools and methods for the uncertainty modeling, control system design verification based non-linear analysis of space launchers. Furthermore, novel control design approaches for their recovery shall be developed. Guaranteed analysis results shall be based on the use of Integral Quadratic Constraints (IQC). Moreover, the same IQC analysis theorems shall be utilized for controller synthesis via re-parameterization of the IQC analysis problem. Both elements will be directly applied and demonstrated on an experimental re-usable lander flight control system using extensive flight test campaigns.
PhD: Development of an optimal experimental strategy for ultrasonic GW-based SHM of aerospace composites.
Supervisors: Dr. Arthur Jones and Dr. Dimitrios Chronopoulos
My current research is focused on developing methodologies based on Bayesian inverse problems to optimise the SHM configuration to detect damage in composite structures.
PhD: Characterisation of Novel Polymers from Terpenes
Supervisors: Davide De Focatiis and Dr Derek Irvine
My research involves undertaking mechanical, thermal and rheological testing of novel renewable polymer materials derived from terpenes. Terpenes can be extracted from existing waste streams and may offer an alternative to current oil-based sources. The aim of this study is to use a variety of miniature specimen evaluation techniques to quantify material behaviour such that potential applications for these new polymers may be identified. This project works closely with the University of Nottingham Chemistry department to establish optimum compositions and manufacturing techniques for creating renewable substitutes that could rival existing oil-based polymers.
PhD: The application of advanced and integrated health monitoring systems to complex, composite systems for aerospace for enhanced life cycle and operational capability
Supervisors: Dr Dimitrios Chronopoulos and Prof Ian Ashcroft
Location: Institute for Aerospace Technology and Composites Research Group
My project focus is in damage detection in composites structures for aerospace application. Understanding the propagation and reflection pattern of waves in structures through finite element modelling of damages in textile composite. The final aim would be to build an industrial system enabling the detection of damages not only on ‘off-line’ aircrafts but also on ‘in-line’ aircrafts.
Graduated from the Université de Technologie de Compiègne (France) – Master in Mechanical Systems Engineering, specialising in modelling and optimization of products and structures.
PhD: Simulation of the Textile Composite Containment Casings Subject to FBO
Supervisors: Dr. Elena Sitnikova and Prof. Shuguang Li
Previous research has been conducted on the subject through an industrially sponsored project for development of composite containment casings for civil aero-engines. The proposed project is to follow some of the important issues left behind from the previous project to help with the establishment of the capability of modelling and simulating such impacts.
PhD: Design for the strength of 3D printed composites
Supervisors: Dr Shuguang Li and Dr Elena Sitnikova
Design for the strength of 3D printed composites. This study is mainly about designing fibre layouts of 3D printed continuous fibre-reinforced composite components, which is aiming to fully exploit the potential of the fibre skeleton within composites.
PhD: 3D printing technology for key load carrying structural parts and components of continuous fibre reinforced polymeric composites
Supervisors: Dr Shuguang Li, Prof Ian Ashcroft, Dr. Arthur Jones and Dr Xianghui Hou
Composite materials have been widely used in aerospace applications to replace metallic structures for weight saving purpose. However, they rarely used in key load carrying parts like joints and lugs. Conventionally, fibres in composites follow straight paths. They have to be cut when holes and notches are introduced for such structural parts, which leads to significant strength dropdown. A new composite design concept of using curvilinear fibres for this type of applications is proposed and the continuous fibre 3D printing technique is employed to implement the design concept. The printed composite material properties are evaluated and mechanical performance of the printed lug as a part of structural joints will be studied.
