Doctoral candidate in Naval Architecture

PhD Topic: Characterization of shipbuilding steels

Description:

Current efforts in the naval architecture are focused on reducing the overall weight to develop a lighter, fuel-efficient and eco-friendly structural solution that reduce carbon emission. Along with the development of lightweight innovative structures, the safety margins are going down, while maritime traffic is increasing. Therefore, there is a need to develop a new class of lightweight steel structures that are compliant with current design rules, but also show excellent performance under accidental limit states such as collision and grounding. We foresee that such structures are built from a combination of normal and high strength steels while absorbing deformation energy through bending and crushing.

Therefore, we are looking for a doctoral student to work on the characterization of steel materials used in shipbuilding. The characterization involves mechanical tests with different tensile coupons that give different stress state (ranging compression, shear, uniaxial tension and plane strain) before material failure and tests with structural components that are scaled representatives of ship structures. The coupon tests should be made with both base and welded materials. For high fidelity, we will use ARAMIS to measure strains on the specimen surfaces. The second part of the thesis work involves numerical modelling of these tests, which involves also the development of material models.

Requirements & Qualifications:

The call is open for candidates with a wide range of backgrounds inside and outside of Estonia. Most importantly, a high level of interest and motivation towards, and deep understanding of, solid and computational mechanics is required. A suitable background may come from mechanical/material engineering, marine engineering, civil engineering, engineering physics, applied or computational mechanics, or related disciplines. Prior experience on working with FE codes LS-DYNA or ABAQUS is a significant advantage and skills with programming tools Matlab, Python or Fortran is considered as a plus as these will be used during the work. The candidate should prove his/her capabilities in writing the technical report and scientific papers in high-quality journals. Experience in collaborative research/publication with the existing TalTech staff is also a plus. The applicant for the position must have a Master’s degree and must fulfil the requirements for doctoral students at the Tallinn University of Technology. 

Employment:

The position is at the Etonian Maritime Academy of Tallinn University of Technology and may include some work as a teaching assistant in our courses. The expected duration of doctoral studies is four years, but a contract is first made for one year, and the extension is subject to the advance of studies and research. The salary is according to the salary system of Tallinn University of Technology.

How to apply for a doctoral candidate position

The application material includes:

1.Motivation letter (maximum one A4 page, important: provide clear, but honest, evidence of your skills related to the job description and requirements above)

2.CV and other proof of scientific activity (publications, conference papers etc.)

3. A certified copy of the master´s degree certificate and an official transcript of records, and their translations, if the originals are not in English. In the first stage, the unofficial documents may also be accepted.

4.An English abstract or summary the MSc thesis.

5. Introducing two referees who can be contacted, directly.

6.Proof of proficiency in English

All material should be submitted in English.

Applications with attachments (in pdf-format) are to be sent to mihkel.korgesaar@taltech.ee no later than 03 July 2020. The position will be fulfilled as soon as a suitable candidate is found.
