Crack-Centered Enrichment for Debonding in Two-Phase Composite Applied to Textile Reinforced Concrete
RÉSUMÉ
This article introduces an enriched finite element representation of crack bridges suitable for simulating the complex damage processes in textile-reinforced concrete. The heterogeneity of both the matrix and the reinforcement occurs at similar length scales of the material structure. Consequently, an improved accuracy of approximation at the hot spots of damage is required to capture the relevant damage mechanisms. This is done by combining the extended finite element method with the variational multiscale approach. While the former is used to define the crack in the matrix, the latter serves for local resolution of the displacement fields in the vicinity of the crack. The approach is exemplified on a 1D example of a tension bar with interacting cracks and on the detailed analysis of debonding in a shear zone of a bending specimen
