Deep penetration of truncated-olive-nose projectile into concrete target

The penetration of a truncated-ogive-nose projectile into semi-infinite concrete targets is studied in this paper. Based on a general definition of the projectile nose factor and the dynamical cavity expansion model, the nose factor of the truncated-ogive-nose projectile is formulated in the present paper to give a theoretical prediction of penetration depth of truncated-ogive-nose projectile in concrete. Theoretical prediction is in excellent agreement with the test results.
