Limit impact velocity of frangible bullet

The article deals with the determination of a limit impact velocity of a frangible bullet. Limit impact velocity is the lower limit impact velocity of the bullet on the hard target, at which the bullet begins to shatter into the fragments. The limit impact velocity of the bullet is one of the criteria to evaluate the frangibility of the frangible bullet. In order to determine the limit impact velocity, the theoretical method or the experimental method or combination of theoretical and experimental method can be used. This article presents the different procedures for determining the limit impact velocity on the basis of the purely theoretical models, the combined theoretical-experimental models based on the frangibility factor and also on the basis of simulation. © 2019 IEEE.
