Özet:

 


In this paper, oblique impact of
ogive nose projectile on 5083-H116 aluminum alloy plates was numerically
investigated. Three parameters such as impact velocity, impact angle and target
configuration were varied to observe their influence on the ballistic
resistance of targets. Based on the results, the oblique angle of impact acts
an important role on the deformation mode of targets. The penetration of
projectile dominates targets under low oblique angle impacts and the
deformation changes from embedment to ricochet as oblique angle increases.
Beside the oblique angle, the ballistic resistance of target is heavily
dependent on impact velocity. Targets are perforated as impact velocity
increases even if oblique angle becomes larger. Target configuration is another
factor on the protective performance which is increased using thicker plates.
The ballistic response of monolithic and double layer targets for the same thickness
is very close each other.
