In this work, the author presents experimental verification of numerical simulation of projectile impact on constructional shields. The experimental tests were performed at a unified test stand to investigate ballistic resistance of materials in field conditions. The stand was developed at the Polish Naval Academy in Gdynia, and then patented. The design of this test stand was based on construction of a ballistic pendulum, fitted to measure: impact force, turn angle of the ballistic pendulum χ, impact velocity and residual velocity of the projectile. All the measurement data were transmitted to a digital oscilloscope and a personal computer. The ballistic velocity of

the shield of V_BL[R] – defined according to Recht’s and Ipson’s method, was compared with V_BL[Z] and V_BL[Z1] – determined according to the author’s method. Verification of numerically simulated ballistic velocity V_RO versus the before-mentioned velocity

was carried out at the 10GHMBA-E620T steel shields impacted by 12.7 mm type B-32 projectiles. The introduced method can be used for determining ballistic thickness h_BL and ballistic velocity V_BL for both homogeneous plates as well as multi-layered constructional shields.
