ON THE PENETRABILITY OF TELESCOPIC PROJECTILES AT VARIOUS SEQUENCE OF MOTION OF ROD AND TUBULAR PARTS
The features of penetration into a semi-infinite steel target of high-density alloy telescopic projectiles are analysed on the basis of numerical modeling within a two-dimensional axisymmetric problem of continuum mechanics. Interaction velocity was from 1400 to 2000 m/s that predetermined the hydrodynamic mode of penetration. Penetrability of telescopic projectiles at various sequence of interaction with a target of their rod and tubular parts is defined. It is shown that depth of the cavity formed in a target is more if at first a rod part of the projectile, and then a tubular part penetrate.
