Abstract: This study determines the mechanical parameters of ABS plastic (acrylonitrile butadiene styrene) by subjecting plates of finite thickness (1–5 mm) to impact loading. A spherical lead particle with a mass of 0.45 g serves as the projectile. A series of experiments provides the basis for mathematical modeling performed with the Reactor3D software package. The results show that the 0.45 g spherical projectile perforates a 3.5-mm-thick ABS plastic plate at an impact velocity of at least 230 m/s. The required impact velocity for perforation ranges from 140 to 300 m/s for ABS plates with thicknesses of 1 to 5 mm. The parameters obtained in this study describe the behavior of finite-thickness plates under impact with an error of less than 5%.

Keywords: ballistic limit, ABS plastic, impact loading, ballistic curve, numerical simulation.
