Numerical Analysis Of The Structural Response Of
Armoured Vehicles Subject To Ballistic Impacts
Author(s)
B. Malherbe & E. Deletombe
Abstract
Ballistic impacts on armoured vehicles cause shock effects that are transmitted in
the structure to the occupants and equipment. These often exceed the human and
systems limits. For a design engineer, reducing the shock levels transmitted to the
occupant and to the onboard equipment requires the use of specific analysis tools
and methods. A complete numerical methodology has been developed by
ONERA-Lille to treat this problem, the main objective of which is to be easily
usable by industrials to improve their structural design. A commercial finite
element code is used, using explicit resolution methods. For computing cost
reasons, the problem must be solved in several steps. In a first step, local impact
on a real 3D armour geometry is simulated. The complete description of the
shock transmission is
