Multi-scale modelling of damage and fracture

Recently, a novel multi-scale modelling approach for damage and fracture problems was presented. This method departs from classical computational homogenization (FE2) and evolves to a discontinuity enriched scheme upon the localization detection. Rotating boundary conditions allow for microscale localization bands to develop. The formulation of the macroscopic cohesive discontinuity enables the micro-macro coupling. The presented scheme is demonstrated on a numerical example which solves both scales in a nested manner up to complete failure
