Abstract
The paper presents some aspects regarding the response of a protective structure under the impact produced by an aerial bomb. The top slab of the protective structure is composed by three layers of different materials: rigid layer made of concrete, elastic layer made by a powdered material (clay, sand etc.) and structural layer made of concrete. The theoretical, although useful, it has not captured all the details regarding the behaviour of a layered slab under such loadings. The paper addresses in terms of numerically study the influence of different parameters of the layers (thickness, material and layout) and weapons of destruction (speed and angle of inclination of the projectile) on the maximum deformation of the base layer of the layered slab.
