Abstract

Abstract

In order to study the influence of projectile material parameters (mainly strength, toughness, etc.) on the penetration depth of hypervelocity penetrating concrete targets, experiments of 93W tungsten alloy column-shaped projectiles with different material properties penetrating concrete targets at 2300–3600 m/s were carried out on a 57/10 two-stage light gas gun. The projectile velocity was measured by a laser velocimetry system, of which the uncertainty is less than 1%. The experimental data of penetration depth and residual projectile length of different projectiles were obtained by computed tomography (CT) diagnosis technology, which can achieve a measurement accuracy of 0.1 mm. Combined with the experimental results and numerical simulation of Euler type finite element method in the literature, the influences of material parameters on the penetration depth and length of the residual projectile at different impact velocities were analyzed. Numerical simulation was carried out based on the AUTODYN software. In the simulation process, tungsten alloy was described by the Grüneisen equation of state and Steinberg constitutive model, while concrete was described by the pressure-porosity equation of state and RHT dynamic damage constitutive model. The conclusions obtained are as follows. (1) If the toughness of the projectile material increases and the strength does not change, the characteristic parameters of the residual projectile, the penetration depth, and the velocity of the corresponding maximum penetration depth do not change significantly. (2) If the strength of the projectile material increases and the toughness is constant, the ability of the projectile to resist erosion can be enhanced, the residual length of the projectile increases, and the critical transition speed increases, thereby increasing the rigid penetration depth and total penetration depth. At the same time, the velocity corresponding to the maximum value of the projectile penetration depth increases.
