Qualification Details

  • MSc. degree in Mechanical Engineering or a related field with excellent results and special interest in modelling, materials and production processes.
  • Prior knowledge of nonlinear solid mechanics, computational methods and material forming.
  • Curious and highly motivated to do interdisciplinary scientific research with a clear industrial application.
  • Working independently and taking ownership for your own research.
  • Strong written and verbal communication skills. Proficiency in English is required, both spoken and written. You need to provide IELTS test results (minimum score 6.5) or TOEFL-iBT (minimum score 90). The latter is not necessary for native speakers of English or whose MSc program was in English.

Responsibilities/Job Description

With the steep rise in sales of electrical vehicles the demand for batteries is growing rapidly. One of the battery technologies is to build the battery pack from cylindrical cells. The battery casing (the so-called battery can) is typically manufactured from steel by deep drawing and wall ironing. This forming process is very critical due to extreme deformations under high surface pressure, friction and temperature variation.

The process is complicated further by the unavoidable anisotropy of the steel sheet, that is reinforced by the large deformations. Under the high surface pressures, forming dies cannot be considered rigid anymore and friction coefficients are no longer constant. Standard simulation tools for sheet forming are therefore not applicable and new models must be developed.

Sometimes the battery cans split during production and currently the cause for this is not well understood. The scientific hypothesis is that material anisotropy plays an important role. The overall objective of this research is to be able to quantify the effect of anisotropy in the sheet material on this failure in battery can production and to optimise process and/or material parameters to minimise probability of failure.

For this project, we are looking for a PhD candidate with relevant expertise at the crossroads of computational mechanics, materials science and production technology. The candidate will report his/her research during bi-weekly meetings of our research group and quarterly meetings with the project partners. The candidate is expected to present his/her results at international scientific conferences and publish them in academic literature. Furthermore, the researcher will be encouraged to tutor MSc students who do their final assignment on sub-projects pertaining to the current research project.

The PhD research will be performed in the chair of Nonlinear Solid Mechanics in close cooperation with the Materials innovation institute M2i and Tata Steel R&D in The Netherlands
