New Method for Calculating the Critical Penetration Velocity (Vo); Technical note

摘要

Research into ballistic protection often requires the determination of some velocity value that characterises a material. Very often this value is stated as the V50, or the velocity at which 50 percent of the projectiles will penetrate the material. More recently, some specifications have called for the determination of a so-called 'V-Nought' or Vsub0 value. There are several papers that provide a means for determining this value by means of iterative schemes. It is the purpose of this paper to present a direct method for calculating Vsub0.
