Abstract

Computational methods for the determination of material properties of microheterogeneous materials including inelastic behaviour are discussed in this contribution. Applications related to this class of problems range over different length scales. These can cover up to six orders of magnitude, ranging from μm to m. Here homogenization concepts are employed to model the constitutive behaviour at macro scales based on results obtained at micro scales. Using the concept of representative volume elements (RVE), the theoretical background is discussed as well as the numerical treatment of the resulting complex, three-dimensional RVEs. Examples show applications within a range of materials used in engineering.
