PhD Student in Mechanical Engineering

The Chair of Nonlinear Solid Mechanics, Faculty of Engineering Technology, University of Twente has an opening for a PhD candidate on micro-mechanical modeling of roughness transfer in steel strip rolling.

Job description
Emerging of the “smart” industry 4.0 technologies challenges the conventional manufacturing processes such as rolling of the steel strips. In this regard, automotive and packaging industries requirements on surface texture of the steel strips are becoming increasingly stringent. Surface texture determines the visual appearance and tribological behavior of the strips. These properties can be controlled/optimized by implementing new technologies, such as laser textured work rolls. These enable customization of the work roll surface texture and thereby the steel strip surface properties. However, these new texturing technologies require deep fundamental know-how and advanced models to optimally deploy them.

The goal of this project is to understand the fundamental physics of the roughness transfer from a textured roll surface to a metal strip surface and to identify determining physical phenomena which take place at the roll-bite contact. Furthermore, it is to develop a physical roughness transfer model that predicts the final surface properties of the strip based on the rolling process parameters. The model will be used by industry to design customized work roll textures for differentiated products and to ensure a robust and efficient transfer of the desired texture to the steel strip.

For this project, we are looking for a PhD candidate with relevant expertise. The candidate will report his/her research during bi-weekly meetings of our research group and quarterly meetings with the industrial partners. The candidate is expected to interact significantly with the industrial partner and present his/her results at the 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.

Your profile
You have obtained a MSc. degree in Mechanical/Material Engineering or a related discipline with excellent results and you have a special interest in modelling and production processes. Prior knowledge in nonlinear solid mechanics, computational methods, material science and experimental methods is required. Ideally, you have a solid background in finite element method, crystal plasticity, sheet metal forming and optimization.

We welcome candidates with strong communication skills who like to present their work at conferences and (project) meetings. Fluency in English is required, both spoken and written. You need to provide IELTS test results (minimum score 6.5), TOEFL-iBT (minimum score 90).
