Abstract
During the operation of the UN and NATO forces in Africa and Asia it appeared
that the equipment held and utilized by these organizations was not proof against
the missiles being shot by rocket propelled grenades. The missiles utilized by the
terrorist organizations belong to the first generation. They have a head with a
shaped charge jet permitting them to pierce up to 300 mm RHA steel.
There are four protection methods against this hazard: reactive armour, thick
proper armour, rod armour and active defence system. The reactive armour
cannot be applied on each kind of vehicle. The thick, proper armour limits other
important features of vehicles. The active defence systems continue to develop,
except the Russian system \“Arena”. Therefore, the fast development of rod
armour appeared. The main task of this armour type is to disturb the symmetry of
the shaped charge jet as a result of the shock that is effective of the deflagration
and not the forming of cumulative jet.
The finite element model of the missile with the cumulative head and its
influence with two types of rod armour will be presented in this article. The
cases of the missile impact with circular and square section for different typical
speeds of missile will be considered.
Keywords: mechanics, finite element method, rods armour, RPG.
1 Introduction
As a result of armed conflicts observation all over the world and actions carried
on by Polish army divisions within a framework of stabilization missions, we can
notice a change in the way of fighting and the usage of available ammunition. It
appears that currently the biggest threat is posed by two types of ammunition.
