Group of mechanics of materials

Group Remmers

Our research group studies the mechanical properties of complex, engineered materials such as fibre reinforced composites and 3D printed materials for lightweight automotive and aerospace applications. In addition, we investigate the mechanical behaviour and fluid flow in fractured porous materials. In all these cases, we develop novel numerical techniques using our own in-house developed Finite Element codes.

Research Profile

The performance of engineered materials such as composites and 3D printed materials can be improved significantly by studying the evolution of their complex microstructures using advanced numerical techniques.

Education is at the heart of our research group. We are offering bachelor and master courses, bachelor and master thesis projects and internship projects.


In order to develop new numerical technique, an in-house developed software platform is a prerequisite. In our research we therefore make extensive use of our own software tools: Dawn and PyFEM. Dawn is our working horse. The development of this C++ finite element code was started in 2002 and now comprises of a variety of element formulations, materials and solver techniques, most of which are not available in commercial or open-source codes. Dawn is built using the Jem-Jive libraries that are developed by Erik Jan Lingen (Dynaflow).

Specific advanced numerical techniques that are incorporated in Dawn are:

  • The partition of unity method (X-FEM)
  • Isogeometric Analysis using the Bezier Extraction technique
  • Model Order Reduction techniques and Wavelet integration
  • Simulation of Additive Manufacturing processes
  • Discrete Dislocations

PyFEM is a small open source finite element code, written in Python 3.0 that we mainly use for prototyping new algorithms and in our educational program. PyFEM was originally developed to accompany the book:
