In this study, impact problems of projectile are investigated using meshless peridynamics analysis. Two impact cases of rigid projectiles having different stiffness values against aluminum target are examined numerically. The problems are simulated in LAMMPS software environments. For each case, numerical parameters affecting perforation patterns of target body are discussed in detail. This work focuses on the effects of numerical parameters of indenter stiffness (k) and critical bond stretch parameter alpha on the perforation patterns of the target for various impact velocities. Numerical results show that larger perforation is produced with the increase of k value of indenter. In addition, it is observed that the impacted plate appears to be more deflected, if greater value of α is employed.
