Title: Numerical Analysis of a Non-circular Cross-sectional Projectile Oblique Penetrating Into Target
Abstract: The oblique penetration movement of a non-circular cross-sectional projectile was analyzed under different incident angle.Finite element simulation of the projectile was performed on the basis of experiments by ANSYS/LS-DYNA.The stress distribution of target deformation and the changing curve of velocity,acceleration and energy at any assumed moment were obtained.Penetration depth was calculated when initial velocity was 1.5 km/s,and its changing curve was obtained under different incident angle.The results of simulation are in good agreement with experimental results.It offers reference for the investigation of extended projectile.
