Modelling and simulation of the laser ablation process
Project description:
LASERS are the backbones of present day innovative engineering applications. Ranging from eye
surgery to manipulation of coatings and surfaces for biomedical implants and aerospace structures
or for the creation of smart materials or nano materials, their application is widespread. The current
capability to simulate LASER processes is constrained by the underlying physics and there exist some
significant gaps in numerical simulation and real-world applications.
The ultimate aim of this project is to improve the laser simulation capability using numerical
modelling. This will be accomplished by developing a simple fundamental model of laser ablation
of titanium metal as a testbed study to support the idea that an ablation process can be predicted
and that the damage occurring due to local heating can be controlled. An understanding of this will
directly contribute to the medical sciences by improving the means of carrying out laser surgery and
allow the design to be cost-effective for bio-medical implants which are widely manufactured using
titanium alloys.
On this project, the student will have a unique opportunity to gain familiarity with a new scientific
simulation tool known as “Molecular Dynamics” simulations and “high performance scientific
computing on local and national facilities”. The project will take advantage of the software such as
“LAMMPS and LIGGGHTS” Furthermore, the project will be undertaken in partnership between the
“School of Engineering at LSBU” as well as the “Orthopaedic Department” of NHS as well as EU
based companies like Multitel and Lasea, and will be highly entertaining and rewarding from the
future employment perspective.
This unique fully-funded full time PhD studentship supports students from any part of the globe and
seeks highly talented candidate in this area. During the research stage, the student will have a
chance to work with key players and be part of the research team developing new simulation tool to
extend the existing knowledge in this area. The position offers unique opportunity to those who aim
to build their career in the direction of analytical modelling skills or who prefer working remotely if
they have exceptional professional or personal circumstances.
Supervisory Team: The successful applicant will be working Dr Saurav Goel who beside LSBU, also
works for Cranfield University and University of Cambridge. He manages two Centres of excellence
namely, “Centre for Doctoral Training in Ultra-Precision Engineering” and “Networkplus in Digitalised
Surface Manufacturing”. As part of this project, you will be benefitted by a wide range of training
tools. Informal enquiries should be directed to Dr Saurav Goel (GoeLs@LSBU.ac.uk). As a PhD student,
you will join the London Centre of Energy Engineering and work alongside a range of new and
experienced PhD students in a collaborative environment.
Requirements: Applicants must be of outstanding academic merit and should have (or be expected
to gain) either a first class or an upper second class Honours degree (or the international equivalent),
or an MSc/MRes with distinction. Enthusiastic and self-motivated candidates from all countries with
a background in either Engineering, Physics or Mathematics or a related discipline are encouraged to
apply. Candidates should be able to demonstrate that they are highly motivated, have excellent
communication skills and undertake challenging tasks using their own initiative. They should have
willingness to go beyond what’s just stated.
Instrumented Nanoindentation for information rich electro-mechanical characterisation
Nanoindentation (ISO 14577 and ASTM E2546–07) is a high resolution technique to precisely
characterise the mechanical behaviour of various materials. Usually, the process of
nanoindentation relies on pressing an unknown substrate by a sharp diamond tip. In its native
form, the process of nanoindentation can be carried out in two modes i.e. load controlled and
displacement controlled. The technique relies purely on establishing mechanical contact to
deform the substrate.
With the advent of new materials, new capabilities are required to evaluate not just mechanical
but also chemical and electric properties of the substrate. This is particularly useful to do a
combined electro mechanical characterisation especially in situation where a contact mode
mechanical loading may not be allowed as it can damage the smaller surfaces such as those
obtained from the museum and in such cases a non-contact electrical characterisation may
instead be performed.
Towards these thoughts a conductive atomic force microscopy has been developed in the past
(https://doi.org/10.1063/1.5044518) however, it looks at very small samples, requires the probe
to be conductive and is still destructive in nature.
A Nanoindentation machines comes equipped with a displacement control to precisely place a
probe at a site as well fitted with a scanning microscope gives good information of the localised
area. As part of this project activity, the aim here is to equip a nanoindenter with unprecedented
capabilities, in particular to bring either a contact or non-contract electrical measurement
capability which will boost the use of this technique for assessment of energy devices in solar area
as well as that of functional coatings.
Thus, the ultimate aim of this project is to instrument electrical capability into the newly bought
nanoindentor at LSBU. An initial idea is to bring capacitive or impedance based measurement
into place such that the indenter can probe a measurand like work function of the localised
area. There is also an opportunity to bring an additional instrumentation for making a
nanoindentation device to behave like an ultra-precision diamond milling system.
On this project, the student will have a unique opportunity to gain familiarity with the
instrumentation process and to learn more about Kelvin probes and its utility in expensive
electronic wafer manufacturing process. The project will have a deep involvement of the UK
leading nanoindentation instrument manufacturing “Micro Materials Limited” who will provide
necessary enabling training to work on the project.
This unique fully-funded full time PhD studentship supports students from any part of the globe
and seeks highly talented candidate in this area.

Understanding of the Rehbinder effect across length scales
Rehbinder in 1928 reported that when a wetted surface is brought into contact with a metallic
surface, it results in reduction of surface energy and hence diminishing strength of the material
(doi:10.1038/1641127a0). The theory in its native form has implications on many fields including
machining, tribology (biomedical implants remain in contact with body fluid), imaging (ultra-sound
imaging) and many more including turbine blades where a metallic part comes undergoes several
wetting cycles. Rehbinder effect in essence, may result in elastic strain, defect formation, plastic
failure, defect formation, diffusion and heat and mass transport – all of which would have
implications on the tribological performance of many mating engineering components. It is likely
that the Rehbinder effect will have a large implication on the coefficient of friction in a broader
sense which would have deep effects across a more-wider range of scientific problems. However,
it is not clear from the literature as to what role does effects like change in length (length scale)
roughness, microstrength of the surface etc plays in influencing the Rehbinder effect.
The ultimate aim of this project is to deepen the current understanding on Rehbinder effect using
numerical modelling (Multiscale modelling using FEA and molecular dynamics) and experimental
approaches (nanoindentation and single point diamond turning). This will be accomplished by
developing a simple fundamental model of nano and micro scratch tests in presence of liquid
media. An understanding of Rehbinder will help augment measures necessary to overcome the
strength degradation of metals as was earlier reported by Rehbinder.
On this project, the student will have a unique opportunity to gain familiarity UK’s national High
performance computing platform like “ARCHER” and will work with a team of scientists at multiple
research labs of global standards. The project will take advantage of the software such as
“LAMMPS”, “Abaqus” and LIGGGHTS”. Also, the project will largely also be benefitted by
experiments performed at LSBU on a Nanoindentation device and that of Single point diamond
machining experiments performed in the UK and in India thus bringing lot of travelling
opportunities for the interested people. The project will involve several key EU wide companies
such as Airbus, Rolls Royce, M-Solv, PVATepla, Stryker to name a few.

Finite element analysis and experiments on hybrid laser assisted high-speed machining
Depending on the specifications (type, pulse, energy
and power), a Laser can either be used for efficient
material removal, forming, bending, joining or for
deposition. Due to being such a versatile tool and the
fact that is a contact-less manufacturing method,
laser manufacturing has gained world-wide
attention. A lot of research in the past has been
done on improving our understanding on the lasermatter interaction but the subject is so rich in
knowledge that is still offering many new insights
and has continued to remain one of the most
researched area in manufacturing at present. A
hybrid manufacturing method relying on laser assistance
is lately gaining popularity. It is also called as thermally assisted machining. The method relies on
traversing a laser source ahead of the cutting tool. The presence of laser heating just ahead of the
cutting makes the cutting material more compliant and amenable to be machined especially,
difficult-to-cut metal alloys. The laser source by preheating the material, enhance plasticity by the
virtue of thermal softening. While the concept, its principal and a limited understanding on this laser
hybrid machining process exist, a lot of questions are still unanswered such as:
1. What should be the ideal horizontal gap between a laser source and the tool tip?
2. Is this distance dependent on the strain rate applied during cutting?
3. What is the correlation between the laser parameters, cutting speed and material’s
absorptivity?
4. Can a combination of laser heating and high pressure jet coolant be used to improve the
machinability even more than what is usually achieved by simple laser machining?
5. In light of the recent knowledge (https://openresearch.lsbu.ac.uk/item/88v54) which
suggests that at specific laser wavelengths, the absorptivity of material decreases with
increased temperature can the laser energy be saved to make the operation energy efficient?
To answer such questions, the project will aim to use analytical and numerical models in conjunction
with the experiments to unravel and elucidate fresh insights onto the laser assisted cutting process.
On this project, the student will have a unique opportunity to gain familiarity with ABAQUS numerical
FEA modelling as well as performing cutting experiments.

PhD Scholarship in Highly Efficient Bifacial Organic Solar Cells
Description: There has been an alarming increase in the atmospheric CO2 content since the mid19th century primarily due to the use of fossil fuels for energy generation. Significant portion of this
is associated with the transport sector, the building sector also accounts for a large portion of
energy. According to the Energy Performance of Buildings Directive by the European Commission
(2019), 40% of the total energy consumption in Europe is due to growth in population and the
building sector. This has led to the adoption of renewable energy sources for power generation for
the building sector. The majority of the solar cells available to the consumer use the classical siliconbased photovoltaic technology, which is expensive and generates very low power under indoor
lighting conditions, making it less attractive for indoor energy harvesting. Therefore, there is a need
for a technology that enables high power outputs under both indoor and outdoor lighting while
being capable of incorporation into building components.
Organic photovoltaics (OPVs) are expected to play a major role in future power generation because
of their capability to deposit solar cells on flexible substrates by printing from solution or spraycoating. Flexible OPVs solar modules are now becoming commercially available and the first largearea installations have been demonstrated for outdoor and indoor power generation. However,
these modules are produced by thermal evaporation in a vacuum which is an expensive technology.
This project aims to develop novel active and interface materials to make low-cost and nextgeneration flexible bifacial organic solar cells by solution methods (ink-jet printing or spray-coating)
for both outdoor and indoor energy harvesting.
The outcomes of this project for the PhD candidate are listed below:
• Investigate the photophysical properties using transient optical spectroscopies;
• gain experience in time-resolved spectroscopy and other characterisation techniques;
• develop the strategies to enhance light absorption, charge generation and extraction;
• fabrication and characterisation of highly efficient bifacial solar cells using non-toxic organic
materials;
• present the findings of the project in international conferences;
• perform high-quality research and publish it as journal articles.
This will be a 3 .5-year fully funded studentship for an EU/UK and overseas applicants who are keen
to conduct research in the development of renewable energy sources at LSBU in the School of
Engineering.
Supervisory Team: The successful applicant will be working with Dr Tariq Sajjad
(https://scholar.google.co.uk/citations?user=cN5jPLMAAAAJ&hl=en ) at LSBU. As a PhD student,

PhD Scholarship in Thermally Activated Delayed Fluorescence (TADF) based Hyperflourescence
OLEDs
Description: Currently lighting is consuming more than 20% of total global energy due to energy
inefficient lighting source. The development of efficient lighting sources will not only have economic
impact but will also address the urgent need to reduce carbon emissions.
Organic light-emitting diodes (OLEDs), a multibillion pound market has the potential to provide
cheap and clean solid-state lighting with minimal environmental impact. The devices with heavy
metal-induced spin-orbital coupling effect, i.e. phosphorescence emitters, and purely organic TADF
emitters, are now regularly been reported with more than 20% external quantum efficiencies.
However, due to the nature of charge transfer and long exciton lifetime, many devices exhibited
broadband emission profiles and serious efficiency roll-offs, this will sacrifice the colour purity for
high-performance displays and efficiency loss at high brightness.
This PhD project, joint between LSBU, University of St Andrews and industrial partner “Edinburgh
Instruments Ltd”, aims to solve above mentioned problems via sensitization process by separating
the exciton generation and recombination sites. For that, PhD student will design, synthesize, and
screen the thermally activated delayed fluorescence (TADF) compounds with short exciton
lifetimes, high radiative and reverse intersystem crossing rate as the sensitizers. To efficiently
sensitize an emitter, the project aims to correlate the energy transfer efficiency with the quantum
yield, rate constants of the sensitizer.
The outcomes of this project for the PhD candidate are listed below:
• synthesis of highly efficient TADF sensitizer;
• gain experience in time-resolved spectroscopy and other characterisation techniques;
• perform experimental measurements to develop the general rules of a good TADF
sensitizer;
• fabrication of highly efficient Hyperflourescence OLEDs;
• present the findings of the project in international conferences;
• perform high-quality research and publish it as journal articles.
This will be a 3.5-year fully funded studentship for an EU/UK and overseas applicants who are keen
to conduct research in TADF Hyperflourescence OLEDs at LSBU in the School of Engineering and
also willing to travel to St Andrews and Edinburgh.

A PhD position sponsored by Airbus in numerical modelling of physical processes, focusing on solving the challenge in landing gear friction by the use of atomic simulation studies is available. Advanced physics and material modelling concepts will be used as an instrument for the modelling. The candidate will have exposure to work with high performance computing (HPC) clusters to write and design their own programming interface to model and assimilate the nature of friction existing at the interface of landing gear during the landing of an aircraft system. The project also provides a rich opportunity to interact with shop floor engineers and management of Airbus, as well as occasional secondment to their site premises in Bristol, visiting International countries to present the research results via International Conferences and to work across various other departments by leveraging advantage of Cranfield Doctoral Training theme.
Carbon-Carbon composites have been deployed in friction braking applications in both Aerospace and Automotive sectors. Friction performance is highly dependent on component design in conjunction with material properties and the control of industrial process parameters. The process fingerprint couple together with material characteristics makes it difficult to predict the durability of braking, its performance and lifetime. Material development and manufacturing process control are both important for achieving enhanced and more consistent brake performance. The performance of materials in friction applications has until now typically been verified by empirical experimental tests. This PhD project takes a different approach compared to earlier investigations as atomic modelling is proposed to complement previous experimental data and enhance existing knowledge on brake wear. Numerical simulations will be performed that captures the physiochemical micro/nano scale processes, which will then be utilised when modelling the brake wear for developing a robust understanding by correlating it to the previous experimental data. In this way, the influence of the smaller scale physics on the wear characteristics can be elucidated. This may lead to proposed changes in material selection and/or manufacturing processes for enhancement of brake performance and durability. Due to the multiscale nature of the physical processes such as oxidation, a dual approach to the modelling is proposed, where the micro/nano scale processes are captured using molecular dynamics simulations, while macroscale features are captured via a finite-element approach. A strong coupling between the two approaches will be ensured. Beside a multi-physics problem, another challenge from a numerical modelling point of view is the multiscale nature; both physico-chemical action and mechanical interaction are important for the friction properties. In addition, the wear is due to the abrasion and fatigue. Cranfield University excels in strategic and applied research. In the latest 2014 Research Excellence Framework (REF), 81% of our research was considered ‘world leading’ or ‘internationally excellent’ in its quality. We are in the top 50 in the world for Engineering - Mechanical, Aeronautical and Manufacturing (QS world rankings 2018). The only other UK institutions in the top 50 are Cambridge, Oxford, Imperial College London and Manchester. Cranfield is a ‘Top 5’ research institute, based on commercial income. We are second only to Imperial College London, in terms of research power in REF 2014. Our world class academics, with proven research records, are in constant touch with industry through research, consultancy and product development. Modelling of material, process and design attributes as a means to simulate performance, hence reducing dependency on physical testing, is not widely developed. Such modelling could contribute to the design of material systems, optimization of components and industrial process design, with the intent of reducing cost and leadtime for product development in addition to improving end product performance in the target vehicles. This research seeks to develop and verify multi-physics modelling techniques to enable end-to-end performance based design of friction systems. You will belong to a new Airbus Landing Systems Engineering Centre (LASEC) at Cranfield University, as well as the separate Centre for Structures Assembly and Intelligent Automation within The School of Aerospace, Transport and Manufacturing. LASEC will be officially launched in March 2020, so you will be part of the “funding team”. Furthermore, working within LASEC will enable frequent contact with Airbus Engineers with valuable access to engineering and physical understanding of the processes in the application area. Funding for conference travel exists. Relocation to Airbus in Filton, Bristol, for a minimum of three months during the 4-year PhD project will be an opportunity for further immersion into the company.

Applications are invited for the above position to join the Manufacturing Metrology Team, as part of the Institute for Advanced Manufacturing, at the University of Nottingham. The Manufacturing Metrology Team conducts fundamental research to enable the next-generation of off-line and in-line metrology tools for advanced manufacturing methods with focus on precision manufacturing and additive manufacturing. More information can be found on our website (www.nottingham.ac.uk/research/manufacturing-metrology). The research within the MMT is developing a camera-based photogrammetry system capable of addressing additive manufacturing applications. By acquiring multiple 2D component images, the system software reconstructs a 3D point cloud which represents the component’s surface geometry. The current prototype software performs the calibration, set-up, data capture, and post-processing tasks relatively slowly – the objective is to develop a system they can deliver process cycle times to industrial requirements. This project will deliver system control software as described above, and will seek to incorporate the principles of information-rich metrology (IRM), developed within MMT. IRM features artificial intelligence (AI) and CAD model recognition (as well as other apriori data), allowing the system performance to be optimised by determining camera and object orientation, accelerating feature-matching, and positioning the cameras during data capture. Candidates must have an excellent degree in (preferably) engineering, physics, computer science, or equivalent, and a PhD (or equivalent experience). Strong skills in optics and computational methods are essential, and specific experience with machine learning is highly desirable. It is also expected that the candidate will demonstrate high level communication and organisational skills and an aptitude for liaison with industrial partners. This full-time post is available from October 2018 and will be offered on a fixed-term contract for a period 6 months. Job share arrangements may be considered. The Faculty of Engineering was the first in the UK to be awarded an Athena Silver SWAN Award, in recognition of our commitment to supporting and advancing women’s careers in Engineering (STEMM).
