The major objective of the research work in the SFB/TRR 136 is to investigate the relationship between material stress and modification to establish process signature components (PSCs). With the help of the latter, a paradigm shift in manufacturing technology is to be initiated: For a desired material modification, for example a change in hardness, the PSCs allow the determination of the material stress to be achieved within the processes in question.
It is obvious that, in addition to work on experimental characterization (see project area C), techniques for a better understanding of the mechanisms occurring in the material and multi-scale modeling and simulation techniques must be used to establish the PSCs. This is where project area M comes in. The aim is not only to develop new models, but also to merge them with existing submodels from the other project areas at the most generally valid level possible. The models are formulated on the basis of mechanical, thermal, chemical and electrical quantities. Thus, project area M contributes significantly to the establishment of suitable PSCs.
