Doctoral Candidate in Computational Mechanics

Aalto University - School of Engineering

We are looking for a doctoral student to work on numerical modelling of fragmentation of quasi-brittle materials. In more detail, you will study breakage and fragmentation of ice blocks under compressive loads. The fragmentation requires novel numerical modelling techniques. Modelling may need to be done on different scales reaching from very high resolution modeling to simplified contact models. Even if the first application is in sea ice, topic relates to other fields that include material fragmentation and fracture, and/or quasi-brittle materials.

You will also participate in development of an in-house code for modelling the fragmentation problem. Our current code is an explicit particle-based simulation code (discrete element method). We are open and flexible with the changes on modelling approaches: study is on complex problem including a multi-fracturing, but initially solid material, and we look for the best solution.

You will work as part of the Arctic Marine and Ice Technology group of the Department of Mechanical Engineering. A central part of our research is numerical modelling accompanied by novel experiments, which are both conducted to study the sea ice failure processes, and ice fracture and fragmentation. As part of the research, you will also attend in performing unique experiments to validate the results of the numerical modelling.


High level of interest and motivation towards, and deep understanding of, solid and computational mechanics is required. Background may come from applied or computational mechanics; material modelling; mechanical, marine, or civil engineering; engineering physics; computer sciences; or other disciplines related to computational mechanics. Prior experience on working with Matlab, C, C++, Python, or Fortran on mechanics is considered a plus. The applicant for the position must have a Master’s degree when starting the work (if you soon finish Master's studies, email us), and must fulfill the requirements for doctoral students at the Aalto University School of Engineering (


The position includes some teaching assistant work. Expected duration of doctoral studies is four years, but a contract is first made for one year, and the extension is subject to advance of studies and research. Salary is according to the salary system of Aalto University.

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).
  2. CV and other proof of scientific activity (publications, conference papers etc.).
  3. A certified copy of master's degree certificate and official transcript of records, and their translations, if the originals are not in Finnish, Swedish, or English.
  4. An English abstract or summary the MSc thesis.
  5. Other supporting documents, like recommendation letters.
  6. Proof of proficiency in Finnish, Swedish, or English if the applicant is not a native speaker of them (see

Applications in English with attachments (in pdf-format) must be submitted through the link below no later than 31 December 2017. The position will be fulfilled as soon as a suitable candidate is found.

Aalto University reserves the right for justified reasons to leave the position open, to extend the application period and to consider candidates who have not submitted applications during the application period.
