In this study,ogive-nose projectile penetration into concrete slabs was tested at initial projectile impact velocities ranging from 1325.0 m/s to 1425.0 m/*** depth of penetration and mass loss of the projectiles were measured,and the residual projectiles were recovered after the penetration *** electron microscopy and metallographic microscopy of the microstructures were performed on various sections and outer surfaces of the projectiles taken from different locations of the residual projectiles,to analyze the intrinsic mechanisms of mass *** analysis results reveal that,during high-speed projectile penetration,projectile abrasion is caused by multiple *** on the cavity expansion theory,a projectile penetration model was established by considering the two main mass loss mechanisms observed in the microscopic *** theoretical predictions of the penetration depth,mass loss rate,and change of projectile head are consistent with the experimental results obtained both in this study and previous research.
