Scale-Bridging Thermodynamic and Kinetic Simulation

The department focuses on the processing of materials: The evaluation of materials microstructures from solidification through thermomechanical processing and, in a generalized sense, during service until failure. Materials microstructures determine their properties, and they are by far not static.

Research

In a scale-bridging approach, we incorporate atomistic methods to develop predictive constitutive models at the mesoscopic scale, which are used to predict macroscopic materials’ properties dependent on the actual state of the microstructure. Among the numerical techniques applied within our department are first-principles methods for phase-stabilities, the CALPHAD method (CALculation of PHAse Diagrams) to calculate phase-stability, molecular dynamics to determine interface properties, and the phase-field method to describe phase transformations and microstructure evolution in crystalline materials. Last, but not least, the Lattice-Boltzmann method is applied to solve surface tension-driven flow. In addition, finite element methods are used, e.g., to predict damage processes in biological tissues.

Recently, the lecture “Phase-Field Theory and Application” given in the winter term has been published in a textbook “Lectures on Phase Field” by SpringerNature (the electronic versions Open Access); the compilation was co-authored by Professor Steinbach and research assistant Hesham Salama, who organized the tutorial sessions in the last years.
