Determination of Dynamic Parameters of ABS Plastic by Loading Finite-Thickness Plates with the Use of a Spherical Particle

Mechanical properties of acrylonitrile butadiene styrene (ABS) plastic have been studied by loading finite-thickness (1–5 mm) plates of this material using a spherical lead particle weighing 0.45 g. We have carried out a series of experiments whose results have been taken as a basis for mathematical simulation with the Reactor3D software package. Comparison of the results indicates that a spherical particle weighing 0.45 g makes a through hole in a 3.5-mm-thick ABS plastic barrier at interaction speeds of at least 230 m/s. The interaction speed required for penetration through ABS plastic barriers 1 to 5 mm in thickness lies in the range 140–300 m/s. The parameters obtained in this study have been shown to be capable of describing the behavior of finite-thickness plates during loading with an accuracy of 5% or better.
