Originální abstrakt
The paper presents numerical simulations of concrete fracture performed on beams of variable size and notch depth using the stochastic meso-level discrete model. The model includes a substantial part of randomness in concrete heterogeneity by accounting for the largest grains when assembling the lattice geometry. The remaining randomness, caused by finer particles and the non-uniformity of the mixing process, is introduced by random fluctuations of material parameters represented by a random field. The results of the stochastic meso-level discrete model are compared with published fracture experiments performed on concrete beams loaded in three-point bending. The effects of randomness in connection with different beam size and notch depth are discussed, as well as observed differences in dissipated energy.
