N2 - The penetration process of Ti-Al 3 Ti metal-intermetallic laminate composites impacted by a projectile was numerically investigated. The ballistic performance, stress distribution, failure and energy absorbing mechanisms of Ti-Al 3 Ti metal-intermetallic laminate composites under high-speed impact were examined in detail. The results show that Ti-Al 3 Ti metal-intermetallic laminate composites under high-speed impact is mostly under tensile stress, since the compressive wave is reflected back as a tensile wave. During projectile penetration, transverse, inclined, and vertical cracks are formed in the Al 3 Ti phase, which can dramatically absorb the kinetic energy of projectile.
