Abstract

Abstract: In present study a three-dimensional finite element simulations were carried out to explore the perforation behaviour of aluminium1100-H12 plates by varying thickness 1, 2, 3, 4 and 5 mm keeping diameter identical, 255 mm, against impact with blunt-nosed projectile having diameter of 19 mm. The numerical results were validated through experimentation (for 1-2 mm thickness) and theoretical results (for 1-5 mm thickness) addressed in the literature and found to be close to each other. The commercial finite element code LS-DYNA was employed to carry out the numerical simulations. It was observed that as the thickness increases ballistic limit increases drastically
