Experimental and metallographic analysis of the energy-absorbing shield subjected to the EFP impact

Abstract

The paper discusses the impact of explosively formed projectiles (EFP) on the process of penetration of armor elements. The protective abilities of homogeneous armor plates and their structure as a result of fast-changing phase transitions have been analyzed. The phenomenon of exposing the analyzed energy-absorbing shield to the EFP impact was also considered in terms of numerical methods. The obtained results constituted the basis for concluding the hydrodynamic effect of the EFP projectile on the armor structure. The extensive metallographic analysis of changes in the structure of steel armor elements within the area of the crater's formation and the punctuated spigot for comparison with the structure of the armor before shooting has been presented.
