Abstract

Abstract

The BPM2D (beam-particle model in two dimensions) was used to simulate the problem of concrete penetration. Three types of beam in the BPM2D were used to create numerical models of concrete. The mechanical properties of each type of beam were randomly allocated according to Weibull distribution to reflect the initial heterogeneity of concrete at the mesoscale level. The failure process of a steel bullet perforating into a concrete panel was analyzed with this model. The comparison of the simulated results with the experimental data and the simulated results of the code LS-DYNA3D demonstrated that the BPM2D was applicable to simulating the dynamic failure problems associated with the transition from continuum to discontinuous media.
