Based on the dynamic spherical cavity expansion(SCE) theory of the concrete materials and the analysis of the experimental data, both the model of the petaling penetration with low speed and the model of the round hole penetration with high speed are constructed to describe the penetration of the grooved-tapered projectile in this paper.
And the model of the petaling penetration with low speed and the model of the round hole penetration with high speed using the SCE theory of the concrete materials are built.
