【 摘 要 】

The presented study deals with the experimental assessment of the effects (i.e. penetration depths) of 7.62 mm × 39 and 7.62 mm × 54 R multipurpose projectiles on various structural and shielding/cover materials. The materials selected for testing were hardwood, softwood, brick and sand. The primary focus of the testing was the effect of projectiles on samples during perpendicular impact at different impact velocities and therefore various impact energies. The secondary aim was to determine and observe projectile properties after target perforation. The observed parameters include the residual energy/velocity and structural properties of the projectiles (e.g. fragmentation).
