Official Course Description:
The successful students can interpret the elastic and plastic behavior of a material using the continuum theory, and describe the stress situation around certain microstructure e.g. at crack tips and near defects. They can also apply the basic concept of homogenization to calculate the effective properties of heterogeneous material. They will have the competence to follow advanced textbooks and scientific literature on nonlinear continuum mechanics and composite mechanics.
