Engineering materials and heterogeneous structures are often characterized by different constitutive behaviors and structural properties, depending on the length scale under consideration. Important material phenomena and structural properties are e.g. aniso-tropic mechanical stiffnesses, electrical conductivity, dissipative characteristics as well as damage mechanisms, delamination behavior and fracture processes. Multi-scale analyses of heterogeneous structures and multi-physical investigations of engineering materials are key aspects of numerical design processes with respect to industrial products and manufacturing. Such numerical descriptions provide the means to achieve a better understanding of multi-physically coupled effects and phenomena across dif-ferent length scales. Thus, the mini-symposium primarily is devoted to multi-scale methods and multi-physical constitutive formulations at different length scales for the design of inelastic materials and heterogeneous structures.

The topics of interest include, but are not limited to:
- Multi-physical constitutive modelling (e.g. thermo-electro-mechanics of inelastic mate-rials at finite deformations)
- Multi-scale modelling of continuous fracture behavior (e.g. spatially homogenized phase-field formulations at different length scales)
- Spatially decoupled homogenization approaches for the non-linear analysis of hetero-geneous structures (e.g. effective material properties of reinforced concrete, fiber-matrix compounds etc.)
- Fully-coupled and multi-physical FE2 methods for numerical investigations of compo-sites (e.g. electro-mechanics of fiber-reinforced elastomeric structures etc.)
