Simulation Research on the Penetration Phenomenon of Long Rod Armour-Piercing Projectile with Different Materials
Using the LS-DYNA software, this paper studied the penetration phenomenon that the long rod armour-piercing projectile with the material of Wf/Zr metallic glass composites and tungsten-alloy penetrating into target. It found that the 93W alloy projectile has a clear mushroom head, and the Wf/Zr metallic glass composite projectile has an acute head and appears “self-sharping” effect obviously. It studied the variation law of the penetration results parameters of the two materials at different penetration initial velocity, and found that the “self-sharping” effect of the Wf/Zr metallic glass composite projectile change to more obvious with the increasing of penetration velocity. It also obtained the change law of the projectile head shape with the penetration velocity.
