Özet:

 



The study presents a comparative numerical
investigation on ballistic performance of ceramic/metal armor structures. 2D
axisymmetric numerical model was developed for ballistic impact simulations
using LS-DYNA® finite element software. The armor structures
included combinations of boron carbide (B4C), Al6061-T6 and 4340
steel constituents. The interfaces in the armor structure were modelled with an
epoxy resin adhesive. In order to define proper material behavior,
Johnson-Holmquist-Ceramics material model for B4C and
Plastic-Kinematic material model for Al6061-T6, 4340 steel and epoxy resin was used. The armor structures were subjected to
7.62 mm ogive-nosed steel projectile impact. In the first section, the
influence of back plate material on the ballistic performance of the armor
structure for bi-layers ceramic/metal configuration (ceramic front face and
metal back plate) was investigated for Al6061-T6 and 4340 steel materials under
same thickness and areal density. In the second section, the effect of removing
half thickness of the metal constituent from the back plate and placing on the
front face was investigated for both Al6061-T6 and 4340 steel materials.
Finally, the influence of adhesive thickness on the ballistic performance of
the armor structure was investigated. Perforation response of the armor
structures were examined in terms of residual velocity of the projectile and
damage mechanisms of the armor structure.
