Abstract. A brief literature review of anti-tank mines and relevant theories is described in this paper. A numerical simulation of a single plate subjected to blast loading in the air, was developed using LS-DYNA and compared with the available experimental results. There appeared to be good correlation between the two, considering that there were many variables that could influence the results. Double-plate structure simulations with an air-filled gap subjected to mine blast were then developed. The experimental and numerical simulation results have shown that using air between the two plates has little influence on either plate (in this work, air is not restrained). The bottom plate deforms mainly due to the impact of the top plate, which deforms more than the gap between the two plates. The simulation without air may then be used as a cheaper alternative. In addition, the numerical results, using CONWEP loading, seemed to be comparable with the experimental results. This analysis has provided skills necessary for future study into the development of numerical simulations in LS-DYNA, which will be crucial for modelling more complex structures.
