چکیده

The response of multi-layered ceramic/steel targets to high velocity impact and penetration has been investigated through experiments and finite element simulations. Damage quantification and the material stresses and velocity histories provided by experiments are used as constraints to be satisfied by numerical simulations of the ballistic penetration event. Experimental and numerical observations demonstrate that the penetration process does not strongly depend on the ceramic material as usually assumed by most investigators. Instead, local and global effects which are related to material performance and structural features have been found to be very important factors that affect the overall target performance. These findings show that meaningful light weight armor design can only be accomplished through a combined experimental/numerical study in which relevant ballistic materials and structures are simulfaneozdsly investigated.

Analytical and Numerical Consideration of Projectile Density Effect on Its Penetration Ability in Alumina Armor

In this paper, penetration of high velocity impact of 4340 steel and tungsten carbide projectiles with specific shapes in to ceramic armor that includes 10 mm alumina (95%) is considered analytically and simulated with Ls-Dyna software. Bernoulli equation used to consider the penetration velocity in ceramics, shows that the penetration is better and easier by increasing projectile density. The ...

Ballistic Testing and Simulation of Co-continuous Ceramic Composite for Body Armour

Co-Continuous Ceramic Composites, referred to as C4, have bi-continuous, interconnected and interpenetrating phases of a metal and ceramic. This bestows such composites with a higher strength to weight ratio compared with traditional composites. In this research work, a C4 composite of AA5083/SiC is fabricated for personal body armour, using gravity infiltration technique. A numerical simulatio...
