    Abstract
  • As a new type of protective armor used to meet the needs of military transport vehicles for protection against projectiles of small kinetic energy, the porous plate can achieve the purpose of light-weight armor protection while ensuring the protective requirement. There has been little research on armor performance of ceramic porous plates at home and abroad. In this work, we simulated the process of KE-projectile penetrating AD95 ceramic plates with holes of different shapes (triangle, circle, square) using the FEM/SPH coupled algorithm based on LS-DYNA3D software. By calculating the protective coefficient of plates with holes of different shapes and comparing the residual velocity and kinetic energy of bullet, we optimized the porous plates to achieve the best protective performance and lightest weight. It was found that the elastic properties of plate with circular holes plate is the best. The FEM/SPH coupling algorithm can simulate the ceramic's cracking and splashing. Besides, the numerically simulated results are in good agreement with the experimental results.
