%X In order to study the mass loss characteristics of projectile high velocity penetration in concrete target, a series of experiments was executed. Unconfined compression strength of concrete target and penetration velocity of projectile are ranging from C30 to C80 and from 800m/s to 1500m/s, respectively. According to experimental results, relation between the projectile's mass loss and the penetration velocity was fitted. Experimental results indicate: (1) for tested projectile and when the penetration speed is lower than 1200 m/s, relation between the projectile mass loss and the square penetration speed V2s is nearly linear, and the mass loss increases with the concrete strength; (2) The best penetration velocity is ranging 1100m/s~1200m/s for projectile made of material 60Si2Mn; at higher velocity, the mass loss increases obviously and the penetration ability decreases rapidly; (3) mass loss occurs at the nose of projectile. When striking velocity is under 1200 m/s, friction is the main factor of mass loss. While melting and friction become main fectors when the striking velocity increases and exceeds a threshold.
