7.1 Ballistics analysis and modelling of ceramic armour subject to KE threat
(Ian Pickup)
In his presentation Ian Pickup focused on the occurrence of dwell and the development of a
system to assess dwell. There is a new programme involving DSTL-PML-FFI to develop a
model for quantitative ballistic investigation, analytical/empirical model an the development of
material models. (see appendix F 4)
7.2 Ceramic Protection (Martin van der Voorde)
Examples of finite element simulations (Autodyn) were shown of projectile-target interactions.
Various projectiles (Preformed fragments, AP mine and blast wave interaction) and various
targets were shown (see appendix F 5)
7.3 Penetration of Tungsten Carbide into steel targets (John Moxnes)
The purpose of this presentation was to show that the simulated penetration capability is
dependant on the numerical solver. it was explained that the J-H damage model appears to be
suitable for modelling the fracture of tungsten carbide although plasticity is not accounted for.
Only the Euler solver is now used. (see appendix F 6)
7.4 Methods for simplifying 3D penetration simulations (Jan Arild Teland)
To simplify 3D penetration simulations, a virtual target can be used. A subroutine is then used
to determine the boundary conditions at the projectile surface. In practice this means that only
the projectile is modelled. The boundary conditions are calculated from the cavity expansion
theory. (see appendix F 7)
7.5 Protection of soft skin vehicles (Ove Dullum)
This presentation described the up-armouring of light vehicles used in combat areas. It
described which sections of the vehicle were to be upgraded and how it was designed. It also
showed how the forces can still incapacitate the occupant even though a vehicle is armoured.
