Experimental and numerical study of the impact interaction of a rigid impactor with a combined target

Resumo

This paper describes the experimental and numerical study of structures used for protection against the harmful effect of bullet and fission elements. A special place among them is taken by spaced-apart structures in which a 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 a fragment of spaced-apart protection are in good agreement with experimental data on both residual forms and deflection.
