The penetration of ceramic targets backed by thin metallic plates when impacted by cylindrical projectiles is studied by a full two-dimensional numerical analysis of the normal impact process. An elasto-plastic behaviour of the materials with a rupture criterion is considered, and an erosion condition is included as a limit situation when the role of the ruptured material in the penetrafion process is limited to purely inertial effects. A detailed picture of the penetration of the target by the impacting projectile is obtained. The results of the numerical analysis are compared with recent experimental observations of the projectile/target interaction using flash X-ray techniques. There is remarkable agreement between the computations and the experimental findings, which confirms the usefulness of the main assumptions of the numerical analysis.
