Increasing the performance of the bullet core by changing the geometry. an experimental and numerical study

This study aims to transfer the entire kinetic energy of a geometrically unique 9 × 19 mm bullet onto the target without compromising its penetration capability. In an era where asymmetric security threats are increasingly prevalent, the newly designed bullet core is proposed as a potential "force multiplier" for security forces. The ANSYS Explicit Dynamics finite element model was employed to investigate the penetration behaviors of both the newly designed and currently used 9 × 19 mm bullets into human tissue analogs. %10 ballistic gelatin was utilized to simulate human tissue in the experiments. In this paper, the penetration effects of the newly designed and in-service 9 × 19 mm bullets on ballistic gelatin were first numerically modeled using finite element methods (FEM). The numerical findings were subsequently validated through experimental testing. Results indicated that the bullet featuring the new geometric design produced greater damage to the ballistic gelatin compared to the conventional design.
