About this role
The Fraunhofer Research Institution for Energy Infrastructures and Geotechnologies IEG conducts applied research in integrated energy infrastructures, geothermal energy and sector coupling. Our research contributes to the development of innovative technologies and sustainable solutions for the energy transition.
Understanding the mechanical behaviour and fracture processes of rocks is essential for the development of Enhanced Geothermal Systems (EGS) . Numerical simulations using the Discrete Element Method (DEM) help investigate rock deformation, fracture initiation and propagation under different geological and stress conditions.
In cooperation with Ruhr University Bochum (Institute for Structural Mechanics) , we are looking for two motivated student research assistants to support our research on DEM modelling and calibration of granite.
