AB  - This project involves the combined use of lattice-type models, x-ray tomography, and imaging techniques to investigate fundamental aspects of fracture of micro-concrete specimens. Tomographic images of the unloaded specimens provide the initial configuration of three-dimensional lattice-type models, which are based on a three-phase representation of the material meso-structure: hardened cement paste matrix, ag- gregate inclusions, and matrix-inclusion interface. In this paper, the lattice model is used to study debonding of a spherical inclusion under far-field uniform tension. It is found that the matrix-inclusion interface is toughened by local heterogeneity in the form of random variations of interface strength. This finding…
