Abstract
Blast analysis using numerical techniques has become increasingly relevant to
anticipate the material response of protective structures. Improvised explosive devices and land mines pose a significant threat to the occupants of armoured vehicles, it’s therefore
important to increase the accuracy of the numerical analysis by incorporating more
sophisticated material models whilst maintaining mathematical tractability. The current
research employs an Arbitrary Lagrangian Eulerian (ALE) numerical technique in the
hydrocode LS-DYNA for the analysis of the blast event. Further, incorporation of a soil
model was carried out for the analysis of a TNT mine blast on a mild steel plate. The primary goals of the research are the implementation of an appropriate soil model and the use of multi-physics finite element analysis to model fluid structure interaction. The agreement with
experimental result is very good and the methodology employed captured some important
aspects of the blast-structure interaction.
