B6: Influence of topology, interfaces and local chemical compositions on the deformations behavior of nanostructures

Influence of topology, interfaces and local chemical compositions on the deformations behavior of nanostructures

Metallic nanostructures and nanostructured materials currently receive much attention due to their often superior mechanical properties compared to bulk materials with larger microstructural features. In Project B6 atomistic simulations are used to study the mechanical properties of individual nano-objects and grain boundaries, as well as their combination (e.g., twinned nanowires, nanocrystalline thin films). The aim is to complement the experimental investigations and provide insights into fundamental deformation mechanisms not readily observable in the experiments, and to derive information for meso- and continuum-scale models of small scale plasticity.
