Computational Models for Ti Composite Armors

2.3: Projectile Impact into Geometrically Ordered Armor Composite, Pyramid Inserts

The following images show the simulation of the penetration of the geometrically ordered armor plate with two layers of Ti-6Al-4V plate and a hard layer in the middle, with the projectile impacting the plate at 2074 ft/sec.

Because of the geometrical variations in armor configuration, various impact locations must be considered.

The simulations indicate that the geometrically ordered features can be used for improvement of the armor resistance to ballistic impact. The image below compares homogeneous Ti-6Al-4V (left), geometrically ordered composite with the hard insert (middle) and the layered configuration (right) having the equivalent volume of the hard material as the geometrically ordered composite.
