Abstract

Abstract

In this work, based on the theory of dynamic spherical cavity expansion, we presented a force model of penetrating projectiles with an elliptical cross-section to study their penetration performance and, using this model, calculated the resistance of the elliptical cross section and the penetration depths. Further, we performed a series of experiments of two typical elliptical cross-sectioned and circular cross-sectioned projectiles with the same mass and length penetrating perpendicularly semi-infinite grout targets at a velocity of 700 m/s to 800 m/s. The results show that the established theoretical model reflected the force condition of the elliptical cross-section and the theoretical results agreed well with the experiment, and that the size of the cross-section had a significant influence on its penetration performance.
- elliptical cross-section projectile,
