ملخص المقالة :
This paper deals with the numerical simulation of segmented projectiles. A segmented projectile is a subset of kinetic energy projectiles. The segmented projectile is made of tungsten and the target is semi-infinite and is made of 4340 steels. Due to the disadvantages of segmented projectiles with, the simulation of segmented projectile with is discussed. Projectiles with aspect ratio greater than one are known as short-rod projectiles. This aspect ratio range forms both the primary and secondary phase of penetration. Numerical simulation was performed by AUTODYN software with Smoothed Particle Hydrodynamic (SPH) method. The use of SPH approach is most consistent with the experimental results. In order to have effective segmented projectiles, greater speeds were used in the simulations. In this range of velocity, due to the hydrodynamic penetration and complete erosion of the rods, the maximum penetration depth is obtained. After a relatively good correlation between the simulation results and the experimental and Hydrocode results, the numerical analysis of the segmented projectiles is performed. The results show an increase in the penetration depth of segmented projectile relative to the continuous type. In the following, the relationship between velocity increase and penetration depth and crater diameter of this type of projectile is investigated. An increase in penetration depth of 40 to 60% has been observed in this type of projectile compared to the continuous projectiles. An increase in penetration depth and crater diameter is observed with increasing impact velocity.
