PN 1: Multiscale simulation of materials

Coordinator: Prof. Dr.-Ing. Christian Miehe
Research Areas: A, B, D, F
Number of projects: 6 + 1 JP seed project

Advanced modeling of material responses is a key requirement to set up predictive computational tools for large-scale analyses of engineering devices and processes. In contrast to the traditional empirical description of material responses, the design of new material properties requires to optimize and understand the influence of the microstructure within the materials. As a result, material design is intrinsically related to modern multiscale methods and homogenization techniques. The development of hierarchical bottom-up and top-down multi-scale approaches is thus considered as the future key simulation technology yielding quantitative reliability for the modeling and design of high-tech materials.

The ultimate vision is the construction of knowledge-based virtual test laboratories, which compose hybrid material systems by bridging both length and time scales as well as discrete and continuum approaches. The key property is the coupling of a macroscopic continuum which is for instance treated by Finite Element Methods (FEM) to an atomistic system dealt with Molecular Dynamics (MD) simulations. In order to model these mechanisms towards a reliable macroscopic overall response design, investigations on a multiscale-cascade of micro- and mesostructures are necessary ranging over a broad spectrum of length and time scales. In Project Network 1 SimTech combines expertise from the area of material science, computational mechanics, numerical mathematics, theoretical, and applied physics.
