Job description ?

  • Vacancy 1: PhD vacancy (3 years) on mechanical testing of recyclable vitrimer composites

    Vitrimers are a groundbreaking development in polymer chemistry. This new class of polymers is neither thermoset, nor thermoplastic, but inherits properties from both polymer classes. Vitrimers were "invented" by Prof. Leibler in Paris in 2011 (https://en.wikipedia.org/wiki/Vitrimers).
    Many applications can be imagined, but the application of vitrimers as the polymer matrix in fibre-reinforced composites, is particularly attractive, because the recycling of fibre-reinforced composites could be drastically improved.

    UGent-MMS is partner in the approved Marie-Curie Innovative Training Networks (ITN) "VITRIMAT - Training in VITRImers: high performance MAterials and Trainees for cutting-edge industrial applications".
    In this project, vitrimers will be applied to manufacture and characterize vitrimer composites. UGent-MMS has a PhD vacancy for 3 years on this large research project with a strong industrial consortium. The purpose is to manufacture and characterize the thermomechanical behaviour of vitrimer composites, by combining a diverse set of experimental testing methods. Those tests should be combined with dedicated instrumentation methods to provide valuable insights into the processing characteristics and thermomechanical behaviour of thermoplastic composites.
    The PhD study is a purely experimental PhD, focussed on manufacturing of small-scale vitrimer composites and mechanical characterization of those composites. The PhD researcher will interact very frequently with the PhD researchers in vitrimer chemistry at the other partners in this project, so it is important to have good notions of polymer chemistry as well.

    Only candidates with a Master degree in Mechanical Engineering, Materials Science, Civil Engineering, (Applied) Physics or similar should apply. You are interested to perform experimental research and to interact and collaborate with industry.

  • Vacancy 2: PhD/postdoc vacancy (4 years) on development of topology optimization algorithms for functionally graded materials

    Wire Arc Additive Manufacturing or WAAM techniques are attracting interest from the manufacturing industry because of their potential to produce 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 produce intermetallic alloys and functionally 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 geometrical shape and the spatial 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 (in order to minimize the warping and geometric tolerances of the produced parts in those moulds).
    It is important to mention that the focus of this vacancy is NOT on the additive manufacturing process itself, nor on the manufacturing simulation or the design simulation of WAAM produced parts. The research question is how the topology of large components can be optimized for certain mechanical properties, if the manufacturing allows for functionally graded material properties across the volume of the part. This optimization should also take into account the physical feasibility to generate certain material phases, dependent on the phase diagrams (e.g. through ThermoCalc simulations) and the alloys that can be manufactured with twin-wire WAAM. From that point on, the optimization strategy can be disconnected from the WAAM manufacturing process itself and becomes a numerical research problem. This means that the classical topology optimization has to be extended with additional field variables that take the spatial variation of material properties into account. Therefore, the profile of the candidate should be much more focussed on computational mechanics and experience with (topology) optimization methods, rather than expertise in AM manufacturing or experimental characterization of AM materials.
    The PhD/postdoc 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/PhD degree in Mechanical Engineering, Materials Science, Civil Engineering, (Applied) Physics or similar should apply. You have a strong background in computational mechanics, you are interested to perform numerical research and to interact and collaborate with industry.

  • Vacancy 3: PhD/postdoc vacancy (4 years) on Ultrasonic assessment of the structural health of Lined Pipelines transporting heavy acids

    Transportation of heavy acidic fluids is often done with specifically designed lined pipelines. The pipelines typically have an outer steel wall (thickness ~15 mm) and an inner ceramic coating (thickness ~1 mm). The proper functioning of such lined pipelines is almost exclusively determined by the inner ceramic coating. In case there would be a leak in the ceramic coating, the acidic fluid will corrode through the outer steel wall in a matter of hours, leading to a full shutdown of the industrial plant.
    Upon installation of the lined pipelines, the ceramic coating could already have a varying quality: e.g. thickness variations, porosity clusters, varying stiffness,... Further, during the operational lifetime of the pipeline, the acidic fluid will gradually erode the ceramic coating (~0.05 mm/year). Hence, it is crucial to properly assess the actual state of the inner ceramic coating at certain time intervals. Current inspection procedures involve a full team of operators which need to go inside the pipeline (after thorough flushing with water) for assessing the quality of the ceramic coating.

    This project focusses on the development of a novel, efficient and in-situ non-destructive test method to monitor the structural integrity of lined pipelines from the outside during their operational lifetime. The ultrasonic technique of interest is the classical contact pulse-echo ultrasound (pipelines are above the ground and accessible). From the ultrasonic response, several signal parameters will be extracted and analyzed in order to estimate the quality of the ceramic coating. In order to cope with the harsh industrial circumstances, this involves the development and implementation of (i) advanced excitation signals (e.g. coded waveforms), (ii) novel signal analysis tools in time/frequency domain and (iii) inversion procedures. In a second stage, the developed method will be implemented in a phased array system with a rolling transducer. Such a system will allow to assess large parts of the lined pipeline in a time-efficient manner.

    This project requires a researcher with a strong interest in instrumental hardware (NI-PXIe platform will be employed), a good background in LabVIEW, as well as a high affinity with advanced signal processing techniques. This project is funded by industry and the final developed device will be tested on-site at the facilities of the industrial partner.

    Only candidates with a Master/PhD degree in Mechanical Engineering, Electrical Engineering, Civil Engineering, (Applied) Physics or similar should apply. You are interested in instrumental physics and signal processing. You have good knowledge of LabVIEW, and preferably also of MATLAB. You are interested to interact with industry and to disseminate your results and findings.

    Contact person ?
