Numerical analysis of blasting effect on concrete

In this study, the blasting effect on concrete is numerically simulated by the 2-D multi-material Eulerian method. Through operator splitting of the governing equations into Lagrangian and Eulerian steps, the Eulerian method is discussed in detail. For the material interface and transport of the mixed Eulerian cells, a modified Young's interface reconstruction algorithm is proposed. The simulation results agree with the experimental data, indicating that the model and algorithm presented in this paper are valid and the numerical method can be used for engineering design.
