BALLISTIC LIMIT OF A THIN PLATE INTERACTING WITH A COMPOUND PROJECTILE

The impact interaction of compound projectiles with thin metal targets is studied, and a method for evaluating the ballistic limit and residual velocity of the projectile is proposed. The compound cylindrical projectile consists of a deformable highly porous nose section and a rigid non-deformable tail section. 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. Calculation results are compared with experimental data. The results are shown to be in good agreement with the results of calculations using available analytical models and experimental data.
