Ballistic limit of a thin plate interacting with a composite projectile

The impact interaction of composite projectiles with thin metal plates is studied, and a method for evaluating the ballistic limit and residual velocity of the projectile is proposed. The composite cylindrical projectile consists of a deformable highly porous nose part and a hard non-deformable tail. The velocity of the projectile is considered in the range 200–850 m/s. The problem is solved numerically in a two-dimensional axisymmetric formulation. The motion of the medium is described using the Lagrange method. The calculation results are compared with experimental data. It is shown that the results obtained are in good agreement with the results of calculations using available analytical models and experimental data.
