Abstract

Bullets can cause various complications such as backwards bounces and splashes. Fragile non-bouncing type of bullets can result in re-splash, as they tend to separate into smaller pieces when hitting difficult targets. In the field of ballistics, the terminal ballistics deals with the analysis of the projectile's behavior upon impact with a denser medium, which is usually gelatin. The aim of this study is to investigate the ballistic value of the Gelatin terminal under the influence of different designs and initial velocity fluctuations using finite element method. The simulations were carried out by changing the initial velocity and different bullet designs were analyzed. Results show that bullet designs with lengths of 175mm, 190mm, and 193mm completely penetrated the target while the design with 220 rows, 2 floors, and 230mm achieved an overall penetration of 200mm. Temporary cavity diameter for bullet design I was found to be 19mm, 23mm, and 30mm respectively, while bullet design II cavity had a lined diameter of 21mm, 24mm, and 11mm. However, a two-story design did not meet the criteria for total penetration, and a new design is required by adding the radius of curvature of the projectile. The coefficient of shape of the projectile is in the range of 0.5.
