This course provides a self-contained and consistent overview on the properties of heterogeneous and nanocrystalline materials based on the theory of composites, so-called micromechanics. The topics concern heterogeneous (one- and multiphase) materials in general (with a special focus on two-phase materials and porous media) as well as nanocrystalline materials, for which the interface may be considered as an extra phase with properties different from the bulk (so-called phase mixture model). The course concerns solid and liquid systems (suspensions, nanofluids).

Students will be able to: correctly use the most important concepts related to the theory of composites (micromechanics) and choose the appropriate micromechanical bounds and model relations for the prediction of effective properties of heterogeneous and nanocrystalline materials grasp the theoretical basis of composite theory (micromechanics) to the degree necessary for a full understanding of the current specialized literature in the field.
