Abstract
This paper describes the experimental and numerical study of the structures used for protection against the harmful effect of bullet and fission elements. A special place among them is taken by separated structures in which the gap between layers is filled with either air or various light materials with good damping, dissipative, and thermophysical properties. The results of the numerical simulation of the fragment of the separated protection are in good agreement with the experimental data on both residual forms and the size of deflections.
