Netherlands: PhD Researcher in Mechanical engineering

Font size: Decrease font Enlarge font


In the automotive industry Finite Element (FE)
simulations are used for formability analyses to reduce the cost and
lead time of new vehicle programmes. An accurate forming analysis of an
automotive part can only be made if the material behaviour and friction
conditions are modelled accurately. For material models, significant
improvements have been made in the last decade, but the accuracy of
friction models is lagging behind. Therefore improved friction models
are needed that can be used in forming simulations of automotive parts.
In order to better understand contact and friction conditions,
experimental and theoretical studies have been performed on the micro
scale trying to take the interaction between single asperities into
account. These micro geometry studies give a more physically correct
relation between the roughness and the friction coefficient. For macro
scale analysis the direct application of micro models is too time
consuming, therefore a scale transition must be made between the micro
and macro model.

To be able to use the micro scale data, macro scale models must be
extended to give a realistic pressure distribution, even with very
course models. Also, the friction model must distinguish between
surface velocities in different directions. The directions and the
surface properties itself will depend on the deformation of e.g. the
sheet material. Robust algorithms must be developed that can take all
of this into account.

The work that has to be performed in this project has a strong
computational bias. The research integrates the field of computational
mechanics and the field of tribology.


We are looking for a PhD student with a background in mechanical
engineering or equivalent, with affiliation to computational mechanics.
The research will be carried out at the University of Twente in The
Netherlands, as co-operation between the chairs of ‘Mechanics of
Forming Processes’ and ‘Surface Technology and Tribology’.
