摘要：

The effect of distributed and localized axisymmetric impulsive loads on three-layer cylindrical shell elements of rocket airframes is studied. Localized axisymmetric impulsive external loads applied along the directrix of a cylindrical shell simulate an explosion of a superquick-action elongated shaped charge. Finite-element modeling of transient processes in such elements under such loads allows correct selection of the physical and mechanical parameters of cylindrical rocket airframes. A significant effect of the behavior of dynamic loads on the transient processes in three-layer cylindrical elements is demonstrated.
