Mechanics of Materials and Structures

Precipitates in solids usually provoke a misfit-stress state due to a misfit – eigenstrain state. Relaxation of this stress state by creep is the relevant mechanism to reduce the often high level of the misfit-stress state. This process is also associated with growth/shrinking of precipitates due to the influence of the stress state on the diffusion process.

Elastoplastic buckling of layered micropillars and microstructures requires a correct interpretation of the experimental results, particularly due to geometric effects, which often are addressed to material properties (cooperation with TU-Vienna, MPI-Düsseldorf).

Modelling concepts for intermetallic titanium aluminides are presented in a review on former concepts, particularly concerning plasticity modified by twinning, together with a concept to understand formation of twins (related to displacive phase transformation (in cooperation with GKSS Geesthacht)).
