On the ballistic performance of metallic materials
Bulletin of Materials Science, 1997 The paper presents a ballistic performance index for metallic armour materials in terms of the commonly determined mechanical properties such as strength and modulus. The index is derived using an energy-balance approach, where the kinetic energy of the projectile is assumed to be absorbed by the elastic and the plastic deformation involved in the ...

Ballistic and physical properties of highly fractured alumina [PDF]
, 2010 It is known that ceramic materials in armour are often shattered by a penetrating projectile and the resistance to penetration is therefore dependent upon the properties of this failed material.

Optimizing the stacking sequence in dual-purpose body armors [PDF]
, 2013 Many police body armor systems are dual purpose, offering both ballistic and knife resistanceby combining a flexible ballistic textile pack with a stiffer knife resistant layer.The two types of protection differ in materials and mechanisms such that each

A study on the energy dissipation of several different CFRP-based targets completely penetrated by a high velocity projectile [PDF]
, 2009 The threat of fragmenting munitions from MANPADS to civilian and military aircraft has, in recent years, become an ever increasing worry. One of the ways to enhance the protection of CFRP-based composites is to add lightweight materials that can provide ...

Optimizing the Thickness Configuration of Bilayer Alumina-Aluminum Armors
Engineering ProceedingsThe ballistic performance of the armor against the projectile impact is affected by the armor configuration. This work investigates the ballistic performance of alumina-aluminum armor impacted by a 20 mm armor-piercing projectile using simulation. A semi-

Measuring the strength of brittle materials by depth-of-penetration testing [PDF]
, 2010 Based on an energy conservation model, the strength offered by a number of brittle materials has been calculated from depth-of-penetration (DOP) test results. Each material was completely penetrated by a tungsten carbide cored projectile of known kinetic
