Arc welding based additive manufacturing or WAAM techniques are attracting interest from the manufacturing industry because of their potential to fabricate large metal components with low cost and short production lead time. This process exists alongside other high deposition rate metal AM technologies such as powder and wire based DED. While these use either laser or an electron beam as energy source to melt a metal powder or wire, WAAM technologies melt metal wire using an electric arc.
The mechanical properties of additively manufactured materials, such as titanium alloy, are comparable to cast or wrought material. It has also been found that twin-wire WAAM has the capability to fabricate intermetallic alloys and functional graded materials.
It is exactly that last feature of functional grading that can be used to tune the mechanical, thermal and thermomechanical properties of large structures, by depositing differently graded material compositions in different areas. Based on this technological asset, the European H2020 project Grade2XL has been approved (https://www.m2i.nl/news/granted-horizon-2020-proposal-on-additive-manufacturing/). The project is coordinated by M2i in the Netherlands, and Ghent University is one of the partners. The current 4-year vacancy will focus on the development of new topology optimization algorithms and software, in order to optimize the shape and distribution of the functional properties across the whole part geometry. Case studies will be provided by the industrial partners, for example tuning the thermal expansion coefficients of very large 3D printed moulds and minimize the warping and geometric tolerances of the produced parts in those moulds.
The PhD study at Ghent University is purely numerical, while the experimental work will be done at the other academic and industrial partners.
Only candidates with a Master degree in Mechanical Engineering, Materials Science, Civil Engineering, (Applied) Physics or similar should apply. You are interested to perform numerical research and to interact and collaborate with industry.
The responsible person at Ghent University is Prof. Wim VAN PAEPEGEM. He has 20 years of experience in mechanics of composites and finite element simulations. More information on the achievements of the research group can be found on http://www.composites.ugent.be/.
Who do we look for?
- you are interested in research and have obtained a Master and/or PhD degree,
- you are interested to interact and collaborate closely with the industrial partners during the research period,
- you have an education in Mechanical Engineering, Civil Engineering, Computational Mechanics, or similar,
- you are familiar with mechanics of materials and experimental or computational techniques (depending on the specific vacancy requirement mentioned above),
- mastering the Dutch language is not a prerequisite, but a good knowledge of English writing and speaking is absolutely required.
What do we offer?
- you will be working in a dynamic environment. Our group has expanded quite fast the last few years and currently, 16 postdoc's and 15 PhD students are working in our group. Besides, 18 PhD students have successfully obtained their PhD degree in the last five years,
- we have extensive experimental and numerical facilities. You will have access to several Linux workstations and a high performance computing cluster to run finite element simulations on 2000+ cores,
- we have good contacts with the regional composite and additive manufacturing industry and regional universities, so you will come into contact with industrial applications of composites and related research in other universities,
- you will get the chance to attend international conferences (e.g. ECCM, ICCM,...) and to present papers on these conferences. For those who are interested, an international exchange with another university is possible. As publications are increasingly important (also for your career afterwards), you are encouraged to publish your results not only on international conferences, but also in peer-reviewed international journals,
- you will have a personal laptop and a private workspace. All PhD students and staff have their office in the same wing of the building. The laboratories are separate in another wing of the same building,
- if you are just graduated (junior PhD student), your net income is about 1950 EUR per month. That is the amount of money that is deposited on your bank account every month (after taxes). If you have a dependent wife/husband and/or children, the salary is raised. Also seniority can be taken into account if you can show former relevant experience. The salary for postdoctoral researchers starts at 2450 EUR net income per month (after taxes).
- the cost for the PhD study itself is very limited. Our education system is very different from for example the system in the United Kingdom. When you start your PhD study, you pay a once-only tuition fee of ca. 1000 EUR, and the rest of your study is free of charge,
- the university offers compensations for public transport (train) and bicycle. The work location can be reached easily by public transport (train and tram/bus),
- a hospitalization insurance policy can be concluded,
- there are a lot of sport accommodations and other benefits (reductions on computer purchase, internet connection, fitness,...) for university personnel,
- there are specific organizations for the international student community in Gent. There are ISAG (International Students Association Ghent) and ESN (European Students Network). They are quite active in organizing all sorts of events (Student Unions and Societies for international students).
Recently, a "China platform" and "India platform" have been founded for the benefit of Chinese and Indian students at Ghent University (see China platform and India Platform).
How to apply?
- you write a detailed Curriculum Vitae in Dutch or English, containing:
- your personal details (name, address, date of birth, nationality,...)
- your education, subject of master thesis and degrees
- your work experience (previous jobs)
- additional skills (finite element software, programming languages, communication skills, ...)
- mastered languages (Dutch, English, French)
- references (previous projects in the domain, published papers,...)
- you send the C.V. by post or e-mail to the following person:
