Abstract. Within the mine-blast research community, there is an increasing desire
to enhance the efficiency and efficacy of mine-resistant vehicles, albeit
in a cost-effective way. An approach that mirrors this requirement
is presented in this paper. The explosion of an antitank
mine is modelled and analysed by using the non-linear dynamics
analysis software, AUTODYN. The initial simulation setup consisted of a
hemispherical charge laid on a ‘perfectly reflective’ plane. Two equations
of state for explosive products were studied, with the first
one being the commonly used empirical equation of state, Jones-Wilkins-Lee
(JWL). The second study applied the ideal gas equation of
state, often used for simplification in complicated models. The mesh
sensitivity study was carried out. Two parameters of blast waves,
namely maximum pressure and specific impulse, are evaluated and compared
with accessible experimental data obtained from CONWEP. Consequently, an explosion
of a mine laid on sand was modelled using JWL
EOS and blast parameters were compared with the previous model.
