Explosive devices are frequently
used in asymmetric combats. They severely threatens not only the armored
vehicles, but also occupants. After detonation of high explosive, blast loads
are transferred through shock waves and they hit the vehicle hull in a few
milliseconds, which might potentially cause serious injuries on the members of
occupants. Anthropomorphic test devices (ATDs) allow for evaluating the
survivability of occupants in armored vehicles subjected to landmine blast in
accordance with associated injury criteria standards. This study examines the
emerging role of numerical simulations in the context of survivability of
combat vehicles in modern warfare. The purpose of this investigation has been
to compare the performance of Hybrid-III 50^th percentile ATD in
numerical simulation with that of full scale blast test. Force and acceleration
time variations were collected from Hybrid-III dummy in blast test. Those data were
then compared with numerical simulation model. Results show that the numerical
simulation results are in agreement with those obtained from experiments.
