Abstract: In this work we seek to improve our understanding of micromechanical phenomena by coupling 3D images of specimens subjected to damage with discrete element computational models. Through this close coupling we might quantify properties such as cement-aggregate interface, the spatial distribution of aggregates, and other features that elude simple measurement. Results show that by producing computational models in which aggregate locations match exactly with real specimens, we are not only able to simulate the damage and fracture patterns observed in the real specimens, but also match the bulk load-deformation and fracture response. Further simulations predicted a relationship between strength and aggregate fraction that was confirmed by further experiments. We view this work as an important step in a movement towards more physical-based modeling.
