Abstract

Explicit finite element code (LS-DYNA3D program) simulation is used to investigate the penetration and perforation behaviour of 6061-T6 aluminum plate and C12K33 carbon fiber reinforced 6061-T6 aluminum metal matrix composite plate when impacted by a tungsten projectile. The plate is impacted by the projectile at the angle of incidence of 0° (i.e. normal direction), and three impact velocities are used, 500m/s, 1000 m/s and 1500m/s. The composite plate has a laminate stacking sequence of (0°/90°)2 and is tested at fiber volume fractions of 5%, 10% and 15%. The carbon fiber laminate is modeled as Hughes-Liu shell elements, wh
