摘要：

In this paper, based on the projectile load analysis using the cavity expansion theory, we simplified the movement and deformation mode of the grooved-tapered projectile in the early stage of its oblique penetration into the concrete as the response behavior of a free beam under transversal and axial transient load at the end, and calculated the shear force, the moment and the yield function of each section of the projectile. In addition, we found out about how the projectile's bending was affected by the projectile body's thickness, yield strength, initial velocity and oblique angle. © 2019, Editorial Staff of EXPLOSION AND SHOCK WAVES.
