ICAMS / Interdisciplinary Centre for Advanced Materials Simulation

Advanced Study Group Input Data and Validation (LWW)

Prof. Dr. Gunther EggelerDr.-Ing. Jan Frenzel

The Advanced Study Group (ASG) Input Data and Validation (IDV) is located at the Chair for Materials Science and Engineering of the Institute for Materials at the Ruhr-Universität Bochum. The advanced study group links the experimental activities at the Chair for Materials Science and Engineering to the modelling efforts of ICAMS. It generates experimental input data and validates model predictions where required.The ASG Input Data and Validation was instrumental in implementing ICAMS at the Ruhr-Universität Bochum, after its foundation in 2007. It continuously interacts with ICAMS scientists in various research projects. Examples for collaborations are:

The ASG study group IDV is presently at the heart of a collaborative research centre on Ni-base superalloy single crystals funded by the German Research Foundation (DFG), SFB/TR 103 which started work in 2012. All three ICAMS departments actively participate in SFB/TR 103 where they promote the field of scale bridging modelling.
