NEW : 6 PhD and postdoc vacancies for Fall 2023
Clearly mention in all your communication the number of the vacancy you are applying for !
Where ?
All vacancies are available in the
"Mechanics of Materials and Structures" research group (UGent-MMS) at Ghent University.
The research group UGent-MMS counts 3 professors and about 30 researchers.
More information can be found in the
slideshow of the research group.
The offices and laboratories of this group are situated in the
south of Ghent (Technologiepark-Zwijnaarde 46,
9052 Zwijnaarde).
Duration ?
All vacancies are full-time job positions. For the duration, see below.
Job description ?
We are looking for a PhD student for a research project on textile modelling.
In this project, the main purpose is to develop a multi-scale textile modelling
framework that allows accurate simulation of textile manufacturing processes
such as yarn unwinding from a bobbin, weft insertion during weaving, stitching
and tufting. This framework is implemented using finite element modelling as
well as virtual fibre modelling. Key here are the dynamics of these systems as
most textile production happens at high speeds. Moreover, the approach should
entail both kinematics as well as mechanics such that predictive simulations
of textile manufacturing can be made. This is still a very new research topic
and many scientific questions remain unanswered.
The PhD researcher will be part of a team of 4 researchers (3 PhD students and one
postdoctoral researcher) who will all work on this large research project.

We are looking for a PhD student for a research project on textile modelling and characterization.
In this project, the main purpose is to develop a multi-scale textile modelling
framework that allows accurate simulation of textile manufacturing processes
such as yarn unwinding from a bobbin, weft insertion during weaving, stitching
and tufting. Besides a strong numerical research focus, there is also an experimental
research track
focusing on advanced mechanical testing of textile materials and their connections, both on
lab-scale and industrial scale (e.g. in-situ measurements on textile machines).
Using techniques such as Digital Image Correlation and high speed camera’s we
gain much better insights into the rate-dependent behaviour of different
textile materials, ranging from yarn to fabric. These measurements will
also serve as input to and validation of the numerical models.
This PhD requires an experimentalist to do the mechanical characterization of textile materials
and their connections at different scales.
The PhD researcher will be part of a team of 4 researchers (3 PhD students and one
postdoctoral researcher) who will all work on this large research project.

Over the past years, UGent-MMS has developed a stand-alone topology optimization code
for additive manufacturing applications. The topology optimization software can deal
with thermo-mechanical coupled problems, combined with multi-material selection. Such
features are not available in any commercial topology optimization code.
The next step is to extend the topology optimization code towards multi-physics applications,
in particular electromagnetic fields in electrical machines.
The purpose of this postdoctoral research is to develop topology optimization strategies
for electromagnetic problems into the existing UGent-MMS topology optimization software.
This requires an advanced knowledge of Python programming, topology optimization strategies
and electromagnetic simulations. The candidate will closely work together with the senior
postdoctoral researcher who developed and is still developing the UGent-MMS topology
optimization software.
Only candidates with a PhD degree in Computational Mechanics, Electrical Engineering or similar should apply.
Additive manufacturing of metal alloys yields great potential for the aerospace industry
(and others) as it allows the generation of geometrically complex structures with high
specific strength, low density and high corrosion resistance. For example,
General Electric has demonstrated the possibility of printing titanium fuel
injectors for their LEAP engine, Boeing incorporated more than 300 printed parts
in their 777X airplane … For such critical applications, the structural quality of
printed parts is of utmost importance. Small deviations in print conditions, e.g.
change in laser fluence, variation in powder quality, non-uniform gas flow, build position …
may result in varying print quality, and even to inferior parts containing porosity, cracks,
residual stress and geometrical deviations, amongst others. Current inspection protocol
involves the use of X-rays, but this is a time-and cost-inefficient method for high-volume
applications.
The RESON-AM project aims at developing a fast, practical and sensitive quality control
technologies for AM metal parts. The project is a close collaboration between several
large industries (Materialise, Siemens and MatchID) and academia (KULeuven and UGent).
Materialise will provide large sets of AM metal parts for use in the project. The project
is funded by SIM-Flanders (Strategic Initiative Materials in Flanders).
At UGent, three researchers will be involved in the project who will focus on the
development and implementation of a quality inspection strategy of AM parts using vibrations.
For this specific vacancy, we search a postdoctoral researcher who will work on data-driven
models for simulating the vibrational behavior of AM metal parts, and for generating a large
and diverse virtual database to enrich the experimental database. Secondly, the researcher
will investigate and implement (supervised) classification methods to identify long-term
trends in the printed parts (e.g. due to drift of laser fluence), and to detect off-nominal
AM parts (e.g. due to presence of large pores) using the virtual and experimental database.
This vacancy applies to mature researchers having a strong background in statistics and
deep learning. Knowledge in vibrational testing is a plus.
We are looking for a PhD student for a research project on microscale mechanical
characterization of fiber reinforced polymer composites using in-situ microscopic
techniques. Much more fundamental insights and measurements at the micro-scale are
necessary to enable fully predictive multi-scale modelling and faster adaptation of
composites. Therefore, we have developed advanced micromechanical test methods for
fibre reinforced polymer composites based on in-situ optical and electron microscopy
during loading. This includes micro-scale Digital Image Correlation (DIC) which gives
full-field strain information at the sub-micron scale, force measurement and
correlation of the damage mechanisms at micro- and macro-scale. This also generates
accurate input data for multi-scale models for composites. This PhD will further
develop and enhance these micromechanical tests and optimize the microscopic
measurement techniques for different types of composites.
Further micromechanical tests will be done to characterize the fibre/matrix interface
in composites. Fibre debonding will be monitored in real-time and different loading
conditions to the interface will be applied.
This PhD requires an experimentalist to do the micromechanical characterization
of the composites. Experience with experimental testing of materials and microscopy
is required. Knowledge of composites and/or instrumentation techniques such as Digital
Image Correlation (DIC) is an advantage.
