The cracking point

Material design: Multi-scale and Multi-field Simulations of Materials

In the quest to understand how materials react under extreme conditions, we model specific materials and their behavior so we can describe their characteristics or design desirable functionality into them.

The material of the future has it all

The material of the future is extremely versatile: robust, cheap, energy-efficient and also intelligent, meaning it can adapt to specific scenarios and applications. Such so-called smart materials have special mechanical properties and respond to changes in their environment, e.g. they adapt their viscosity to magnetic fields, generate mechanical tension from electrical fields or expand at elevated temperatures. Many technical achievements, in information technology or medicine, for instance, would be impossible without newly-developed ceramics, polymers, and bio-compatible or hybrid materials.

Advanced modeling holds the key

Advanced modeling of material responses is a key requirement for developing predictive computational tools that make large-scale analyses of engineering devices and processes possible. In contrast to the traditional empirical description of material responses, the design of new material properties requires optimizing and understanding how the materials are influenced by their microstructures.

Thus, material design is intrinsically related to modern multi-scale methods and homogenization techniques. The development of hierarchical bottom-up and top-down multi-scale approaches is therefore regarded as the key simulation technology of the future that will yield quantitative reliability for modeling and designing high-tech materials.

Virtual laboratories

Our ultimate vision is to construct  knowledge-based, virtual test laboratories that will make it possible to compose hybrid material systems by bridging both length and time scales as well as discrete and continuum approaches.

Thereby the research projects in the long term can make a decisive contribution to meet the challenge of sustainable economy and production.
