In this contribution, we present a multi-scale fracture framework, allowing us to con- sider individual fracture behaviour on a macro and a micro scale. We follow the style of FEM2 /IGA2 -concept for macroscopically modeling complex materials with heterogeneities on the micro-scale, see Schmidt et al. [1]. In this talk we address additionally the established phase-field method for fracture mechanics, see Hesch et al. [2]. To be specific, we apply the macroscopic deformation at a given point to a epresentative volume element via suitable boundary conditions and super-impose the macro-phasefield in this point onto the micro-phasefield of the RVE. Introdcing a suitable homogenization technique including different fracture dissipations on the micro- and macro-scale, we obtain an energy preserving formulation. Moreover, we are able to derive consistent linearization of macroscopic stresses, the phase-field driving force and multi-field contributions for the Newton-Raphson iteration. The dual phase-field allows by choosing sufficient transition criteria to model a variety of effects within the fracture and damaging field, which are exemplary demonstrated in a variety of simulations, e.g. two-dimensional fracture mode tests for the macro-scale and classical deformation benchmarks. We investigate different crack growth behaviours, from pure micro- or macro-fracture to combined or accumulated fracture and draw comparisons to other damaging models. REFERENCES [1] F. Schmidt, M.
