The main objective of
this paper is to investigate damage resistance of Armox 500T and Aluminum
7075-T6 plates subjected to drop-weight and ballistic impact loads.
Investigating the behavior of structures under the low or the high velocity
impact loads is an important research topic. The study of materials and their
combinations provides fundamental understanding of many engineering structures.
In this study, firstly drop weight and ballistic impact resistance of the
Armox-500T and Al7075-T6 materials was examined. Ballistic impact analyses were
carried out using 7.62 API projectiles with an initial velocity of 800 m/s.
During the drop-weight analyses, the drop of 5.5 kg weight from the 800 mm
distance was modeled. The situations at which target plates of different
thickness can be fully penetrated or not to be fully penetrated by the
projectile, the final (residual) velocities in the fully penetrated plates and
the amount of energy absorbed by the target plates were investigated. 6.72 API
projectiles with an initial velocity of 800 m/s could not fully penetrated the
10 mm Armox-500T target and 26 mm Al7075-T6 target. When drop-weight results
are concerned, the maximum impact loads of the Armox-500T target is higher than
the Al7075-T6, and the deformation amount is less. In addition, 10 different
hybrid models, which consist of various combination of Armox 500T and Al7075-T6
materials in different thicknesses and orientations, have been defined. These
models were compared with each other and models that are more resistant to
ballistic impact loads were determined. M4, M7, M9, and M10 models were found
to be more resistant to the ballistic impact loads than other models.
