Martec Limited has developed considerable
expertise in modeling the effects of landmines on
people and equipment. Martec’s software, Chinook,
includes the ability to accurately predict target
loading due to landmines buried in different soil
types and conditions. The software's capabilities
include the ability to accurately capture the explosion
physics using state-of-the-art models. Of particular
importance to developing protective measures is the
effect that soil composition has on target loading.
Typically, wet soils transfer more energy from the
initial blast to nearby targets than corresponding
dry soil mixtures. This can mean the difference between
a vehicle being slightly damages or being completely
disabled.
These modeling capabilities have been validated through
comparisons with experiments performed at Canadian
Department of National Defence test facilities. This
includes simulations of trials involving a ballistic
pendulum apparatus, where the maximum height obtained
by a pendulum arm subjected to a landmine blast is
measured to determine the energy transferred by a
buried charge. Martec has also successfully predicted
the response of armoured plating to typical anti-vehicular
landmines.
