Abstract:

The paper deals with the dynamic process of local destruction of an object of armor protection. It is modeled as an object of destruction in the form of a spherical shell, and the threat is represented in the form of a metal round bar. Formulas are given and an estimate of the acceleration rate at which the object of armor protection is guaranteed to lose continuity is made. It is shown that if the rod has a tip covered with a layer of iridium, then under certain conditions, due to the fact that this metal has a high dynamic viscosity under intense loads, the object of armor protection is highly likely to be hit.
