A three-dimensional lattice model is used to evaluate the fracture behavior of Strain- Hardening Cementitious Composites (SHCC) in tension. Individual fibers are explicitly represented within the random lattice representation of the cement-based matrix. Comparisons are made with experimental measurements of crack openings and their evolution during increasing levels of tensile strain. The preliminary results indicate crack openings are correlated with characteristics of the fiber distribution.
