Doctoral student in Applied/Computational Mechanics

Multiphysics Numerical Modelling of Advanced Rock Drilling Technologies is a new 5-year project funded by Academy of Finland (http://www.aka.fi/en/about-us/media/press-releases/2016/academy-grants/). The background for this project lies in the search for new advanced and more efficient rock drilling technologies. In traditional rock drilling methods, the rock breakage is caused by mechanical loading only. Advanced drilling technologies use some other physical agents, such as microwaves or plasma shocks and water jets, to weaken the rock before (or during) the application of mechanical loading. The aim of the project is to develop numerical methods for modelling these advanced rock drilling technologies.
Job description: In the project described above, the fundamental process to be modelled by the doctoral student is the dynamic tool-rock interaction process along with the weakening effect of an external physical agent. The first task is to develop a constitutive model for rock (based on FEM and/or DEM) that incorporates the rock microstructure description at the level needed for modelling the weakening/damaging effects due to the assisting agents (microwave heating, plasma shocks etc.). The second task is to develop a numerical method that couples the mechanical breakage to the damaging effects caused by the assisting physical agents in order to simulate the advanced rock drilling process.

Clearly, this is a multiphysics modelling problem which involves solving several types of physical field problems. The validation of the developed methods involves experiments.

The work will be supervised by Academy Research Fellow Timo Saksala. The position will be located at the Department of Civil Engineering (TUT).
Requirements: The candidate should hold MSc degree in a suitable field (Mechanical Engineering, Geotechnical Engineering, Computational Materials Science etc.).

A theoretically oriented, problem-solving mind definitely makes life easier with this job. Moreover, a good command in programming with Fortran, Matlab or Python etc. is beneficial.

Finally, the doctoral student usually has assisting teaching duties amounting approximately to 5% of the annual working hours.
Salary: The salary will be based on both the job demands and the employee's personal performance in accordance with the University Salary System. According to the criteria applied to teaching and research staff, the position of a doctoral student is placed on the job demands levels 1-4. In addition, employees receive performance based salary.
Trial period: Trial period of four (4) months applies.
Other: The position is expected to start in January 2nd, 2017, or as mutually agreed upon by both parties. Doctoral students are expected to graduate within four years (the funding period is 4 years). The candidate will be working on the TUT Hervanta campus, Tampere, Finland.
For more information, please contact: Academy Research Fellow Timo Saksala by email timo.saksala@tut.fi.
How to apply: Applications must be submitted by TUT online application form. The closing date for
applications is 3rd October 2016. Applications and all accompanying documentation must be in English.

The application should include a letter of motivation (max. one A4 page), CV, publication list and transcript of record (Master's degree studies).
