| Abstract | Modern personnel armour are composite consisting of a front ceramic plate and a backing plate typically made of a metal. In most cases, the armour system needs to be able to maintain its integrity under multiple impacts. A numerical investigation is presented in this work to study the ballistic performance of Aluminum Oxide (Al203) ceramic plates bonded to a backing subjected to multi-hit impacts according the NATO AEP-55 STANG 4569 standard. Numerical models were developed using the explicit finite element code LS-DYNA, which possesses contact, erosion and material failure capabilities particularly suitable for ballistic simulation. The Johnson-Holmquist piecewise linear plasticity and plastic kinematic constitutive material models were used to model the materials behaviors of the ceramic, projectile and backing materials, respectively. |
