Abstract: Numerical models can be used to link the material parameters of fiber reinforced cement composites (FRCC) to performance measures defined at the composite scale, such as strength, toughness, and crack size distributions. The effectiveness of such model-based simulation depends not only on the accuracy and robustness of the analysis procedures, but also on facilitating the overall process of model construction, analysis, and results interpretation. The goal is to support the creative design of materials and structural components exposed to severe loading and environmental conditions. This paper discusses the direct modeling of individual fibers and the fiber-matrix interface, within a random lattice representation of the material matrix. Using this multi-scale simulation framework, models are proposed for analyzing FRCC subjected to drying environments. The recent extension of this framework to three dimensions is described, along with its use in studying the restraining effects of fibers on concrete shrinkage.
