Abstract
The use of armor structures is constantly growing in the world market due to the need for protection in the various forms of conflict in various regions of the planet. The ballistic market is increasingly requiring more efficient shielding structures, maximizing armor resistance with the lowest possible weight, so there are several methodologies for the optimization of these structures, such as: Analytical, Numerical and Experimental Methods . In this work, Florence's analytical method was used to achieve the optimization of a hard-ductile shield with the materials available in the market. The Florence analytical method was developed in MatLab® environment for the subsequent comparison between the various analysis conditions in order to reach the most efficient shielding structure. The analytical method used focuses on the relation between the residual velocity of the impacted projectile and the surface density of the projected structure. The use of such a method is the initial step for the design of a ballistic shield, since the use of numerical methods is shown to be complex in the beginning and experimental methods are time consuming and costly to develop. That said the analytical method is the best way to start a shielding project because this provides important information for the use of numerical methods and significantly reduces the number of experiments performed, thus consequently reducing cost and time demanded in the final phase development.
