Ceramic plates penetration

The control of the properties and its effects were analyzed with the developed computational method. It is considered a stress-strain curve given by the power law and the deflection profile of the plate given by where is the maximum deflection of the dimple shape, is the radius of the projectile, dimensionless is a deflection profile constant that can be determined experimentally, and is the radial distance of the impacting projectile center. In addition, the effect of the thickness of the plate together with the radial distance of the impact center is presented in Figure 7. The used meshfree Lagrangian technique SPH is to overcome problems of mesh tangling and remove the requirement for the use of erosion algorithms. Another advantage of using backing material is to improve the ballistic performance of ceramics by preventing its premature failure. However, one was destroyed by friendly fire on March 25, killing two crew members after a HESH round detonated on the commander's hatch causing high velocity fragments to enter the turret.

Call us , we are always happy to consult with you! Ranger Body Armor was developed for the American military in Finishing the vest- The shells for the panels are sewn together in the same standard industrial sewing machines and standard sewing practices. Check The Latest Price on Amazon! An improved version, the Infantrie-Panzer, was introduced in , with hooks for equipment. This is because the impact force of these objects stays concentrated in a relatively small area, allowing them to puncture the fiber layers of most bullet-resistant fabrics.

SAPI plates were first designed and used by the United States military as a kind of ballistic vest, known as Interceptor body armor. In other projects Wikimedia Commons. This complexity requires very elaborate bio-morphic backing material systems for accurate ballistic and stab armor testing. Compliant with NIJ
