Numerical simulation of ballistic impact response on composite materials for different shape of projectiles

In this present work, the ballistic impact resistance of Uni-directional E-Glass/Epoxy laminates is numerically simulated for various projectile nose shapes. For this purpose, a finite element explicit software package, ABAQUS/CAE, is used to simulate the 3D model of the Specimen and Bullet. The dynamic analysis is done for four different layup configurations, (i) [0/90/0/90-rep-], (ii) [45/-45/45/-45-rep-], (iii) [0/90/0/90-sym-], and (iv) [45/-45/45/-45-sym-]. These target plates are tested against projectile nose shapes such as flat, hemispherical, ogival, conical, and spherical. The residual velocities, the kinetic energy of the projectile have been plotted for different ply orientations and nose shapes, and they are compared to get a clear picture of the effect of nose shapes of projectiles.
