Micro Abstract:
The variational multiscale (VMS) method by Hughes et al. is a well-established framework for the analysis of nonlinear heterogeneous materials and is capable of tackling strain localization in the multiscale framework. In this contribution, we propose a non-intrusive setting of the VMS approach to be applied to the phase-field formulation of fracture. The proposed two-scale procedure yields results comparable to the single-scale solution, yet they are obtained with much superior efficiency.
