SOME ANALYTICAL AND COMPUTATIONAL ESTIMATES OF PARAMETERS OF OPTIMAL PROTECTIVE PLATE STRUCTURE
The optimization problem of shield (protective plate) structure having given thickness and consisting from several layers is considered. It is supposed that these layers are made from different materials with given properties. The order and thicknesses of layers are determined from the condition of maximization of ballistic limit velocity of the high-speed striker penetrating into the plate. The analytical expressions for the ballistic limit velocity and the relations describing the shield structure are derived, the optimal solutions for the given set of materials and different values of problem parameters are obtained. The theoretical estimation of the parameter characterizing the head part of striker is performed.
