Description	Virtual testing of composite materials is, compared to a conventional experimental analysis, less time consuming, and it can very clearly reveal the failure mode. Therefore, it can be used for an optimization of the shape and amount of aggregates. Unlike the basic analytical homogenization methods, numerical modeling can predict the strength of the material and energy needed for the crack propagation. In our study three-point bending and splitting tests, by means of 2D plane-stress nonlinear finite element analysis utilizing isotropic damage model, were simulated. The results of the analysis indicate that angular aggregates of bigger size contribute to an increased fracture energy of the mortars, while the mortars containing fine round aggregates exhibit higher strength due to absence of stress concentrations around the grains.
