Protection of an explosion chamber against fracture by a detonation wave

The results of numerical simulation of the protective properties of layered and porous shields that are used to reduce peak stresses and to prevent failure of the walls of an explosion chamber under detonation loading are presented. It is shown that porous shields have stronger protective properties than layered shields of the same thickness. Institute of Applied Mathematics and Mechanics, Tomsk 634050.
