Increasing performance by changing the geometry of bullet cores

This study aims to transfer all the kinetic energy of the 9×19 mm bullet, which has a geometrically unique design, onto the target without losing its penetration ability. In this way, the newly designed bullet core can be added to the security forces as a "force multiplier" in today's world's increasingly asymmetric security threats. The study examined the penetration effects of the currently used bullets and the newly designed bullets on human tissue using the ANSYS Explicit Dynamic finite element model. 10% ballistic gelatin was used to simulate human tissue. First, the penetration effects of the newly designed and currently used 9×19 mm bullet cores on ballistic gelatin were numerically modeled with the finite element method (FEM). Afterwards, this numerical analysis was also verified experimentally. According to the obtained results, it was observed that the bullet with the new design caused more damage to the ballistic gelatin. In addition, it was determined that the amount of energy transmitted to the target by this new bullet design was higher and the effects it created on the target were more destructive.
