Abstract
Modern technological processes demand for high performance materials. For such pro-
cesses, the relation between microstructure, properties and the macroscopic constitutive
response is crucial. To interpret and model heterogeneous metallic materials enabling us
to design optimal structural properties it is essential to analyze and understand the inter-
actions of different, even competing mechanisms at different length scales. However, the
development of various microstructures depending on the chemical composition, load-
ing path and loading rate, makes it a difficult task to elaborate directly comprehensive
constitutive models. In this regard it is important to develop and identify sophisticated
models for specific mechanisms at the relevant scales and additionally for scale bridging.
However, an extended and valid understanding of the different mechanisms can only
be obtained in a multidisciplinary context, where experimental observations and model
concepts are linked strongly. In this regard, the talk will address different experimental
and numerical investigations of heterogeneous materials at different length scales, focus-
ing in particular on the modeling of microstructures, material instabilities as well as its
application in technological production processes.
