Abstract: The dynamic fracture process of concrete is simulated with the BPM^2D (Beam-Particle Model in Two Dimensions) which is based on DEM in combination with FEM. In the BPM three types of beam are chosen to be the concrete specimens to simulate. The mechanical properties of the elements of each and every beam vary with their strain-rate and are randomly assigned according to Weibull distribution so as to model the initial heterogeneity of concrete at microscale level. The failure process of a concrete panel under dynamic impact was analyzed by this model. The stress wave propagation in concrete at different impact velocities was displayed. A comparison of the simulated results with experimental data declares that the BPM^2D is available to simulate the dynamic failure of brittle materials.
