Ceramic/composite armours are being increasingly utilized as protective structures against medium calibre projectiles due to its high efficiency compared to monolithic steel armours. Armour design optimization use to be helped by the utilization of different design tools, either analytical models that simulate the penetration process by one-dimensional simple equations or numerical hydrocodes that simulate the process by finite element or finite difference methods. An accurate description of the ballistic impact of a medium calibre projectile onto a ceramic/composite armour is far from being fully solved neither by existing analytical models nor by commercial hydrocodes, due to the lack of data of the mechanical behaviour of materials involved, and specially of failure criteria at high strain rates. The paper presents some advances on the simulation of the penetration process of medium calibre projectiles on ceramic/composite armours, both by analytical and numerical approaches, that agree well with empirical data, thus providing design tools that permit optimum armour design with a reduced number of actual firing tests.
