The dynamic failure behavior of fiber reinforced cementitious composites (FRCC) is sim- ulated using an irregular lattice model. During fracture process, the visco-plastic contributions rep- resent the rate dependency of the matrix phase. Individual fibers are introduced within the lattice framework for the explicit modeling of these heterogenous features of the composites. Three-point bending tests are simulated for a plain mortar beam and FRCC beams with two different fiber volume fractions. Crack patterns and load responses are presented for the evaluation of failure characteris- tics. The results provide qualitative understandings of the failure features of FRCC structures under dynamic loading conditions.
