small-caliber ammunition, 5.56 × 45 mm, penetration, terminal ballistics, simulationAbstract
The analysis was performed on six commonly used 5.56 × 45 mm projectile types (M193, M855, M855A1, L31A1, M995, and AP45). The projectile’s impact velocity (chosen as 900 m/s) was the same in the examination process. This made it possible to assess how the projectile’s design has affected its performance against a hard steel target. These evaluations included numerical simulations (Ansys Autodyn) of projectile impacts. Using the available experimental data, the materials in the computational model were first validated. A short description and CAD model of projectiles is also given. Relevant conclusions were reported.
