Engineering structures are often characterized by different structural properties, depending on the length scale under consideration. Fiber reinforced composites are determined, eg, by a heterogeneous microstructure, but are sufficiently described by homogeneous characteristics at their macroscopic level. Moreover, different loading situations, eg, of thermal or mechanical nature, require the consideration of multiphysical equilibrium states. The challenging engineering task is the computation of the effective material properties of these different loading scenarios. The contribution at hand introduces a finite thermo-elastic two-scale analysis, where the effective macroscopic material properties are computed in a decoupled manner with respect to the different length scales.
