Abstract—The increasing threat of a blast explosion from high explosive devices, such as trinitro-toluene (TNT) encapsulated by a steel casing shell, makes the study of the blast phenomenon more important. In this paper, a study of the blast phenomenon due to TNT was studied. Both experimental and numerical analyses were done. The explosive system comprises 80 kg of TNT encapsulated by a steel casing shell, with the total weight of the device being 250 kg. Experimental results showed that the blast velocity was found to be 827 m/s, while the shrapnel velocity was 802 m/s. Numerical analysis using LS-DYNA simulated the explosion sequences in detail and predicted the maximum velocity of the shrapnel.
