J. Mech. Eng. Rob. Res.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.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Blast explosion,LS-DYNA,Steel casing shell,TNT[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]The authors wish to thank the Ministry of Defence, Republic of Indonesia through Defense Research and Development Agency, PT.
