[Search for optimal combinations of the hygienic and protective characteristics of body armors].

The protective composition of a body armor is generally characterized by two major parameters--the area and level of protection, i.e. resistance to bullets and fragments. These characteristics directly depend on the mass of a body armor and the sizes of the body's screening. The positive protective characteristics simultaneously have a negative impact on the most important hygienic indices of a body armor, such as convenience and easiness-to-use. The optimum combination of protective and performance characteristics of body armors makes a compromise between their mass and the level of protection.
