The ballistic limit or limit velocity is the velocity required for a particular projectile to reliably (at least 50% of the time) penetrate a particular piece of material. In other words, a given projectile will not pierce a given target when the projectile velocity is lower than the ballistic limit. The term ballistic limit is used specifically in the context of armor; limit velocity is used in other contexts. The ballistic limit equation for laminates, as derived by Reid and Wen is as follows: where Additionally, the ballistic limit for small-caliber into homogeneous armor by TM5-855-1 is:

  • The ballistic limit or limit velocity is the velocity required for a particular projectile to reliably (at least 50% of the time) penetrate a particular piece of material. In other words, a given projectile will not pierce a given target when the projectile velocity is lower than the ballistic limit. The term ballistic limit is used specifically in the context of armor; limit velocity is used in other contexts. The ballistic limit equation for laminates, as derived by Reid and Wen is as follows: where * is the ballistic limit * is a projectile constant determined experimentally * is the density of the laminate * is the static linear elastic compression limit * is the diameter of the projectile * is the thickness of the laminate * is the mass of the projectile Additionally, the ballistic limit for small-caliber into homogeneous armor by TM5-855-1 is: where * is the ballistic limit velocity in fps * is the caliber of the projectile, in inches * is the thickness of the homogeneous armor (valid from BHN 360 - 440) in inches * is the angle of obliquity * is the weight of the projetile, in lbs
