Penetration models and calculating algorithms are presented, describing the\ndynamics and fracture of composite armor shields penetrated by high-speed small\narms. A shield considered consists of hard (metal or ceramic) facing and\nmultilayered fabric backing. A simple formula is proved for the projectile\nresidual velocity after perforation of a thin facing. A new plastic-flow jet\nmodel is proposed for calculating penetration dynamics in the case of a thick\nfacing of ceramic or metal-ceramic FGM materials. By bringing together the\ndeveloped models into a calculating algorithm, a computer tool is designed\nenabling simulations of penetration processes in the above-mentioned shields\nand analysis of optimization problems. Some results of computer simulation are\npresented. It is revealed in particular that strength proof of pliable backing\ncan be better as compared with more rigid backing. Comparison of calculations\nand test data shows sufficient applicability of the models and the tool.\n
