- The process of penetration of B-32 type 12.7 mm armour piercing bullet into one-layered and two-layered of 20 mm thickness RHA armour, is presented. Analysis was carried out with AUTODYN 5 programme and with the use of the SPH method. Projectile and armour strains occurring in the subsequent time period for seven variants with different material parameters of projectile and dimensions of armour, are shown. The influence of different material parameters of the projectile on its capability of armour penetration is presented here. It was proved that two times higher yield stress of projectile material causes almost three-fold improvement of depth of penetration and the bulging of the armour. In its initial phase of the projectile penetration into armour (0÷0.04 ms) the kinetic energy of the projectile rises together with the decrease of yield stress of its material. Computer simulation showed that capability of protection of one-layered RHA armour is higher than in case of two-layered RHA armour.
