Considered sharing FEM and BEM for the calculation of the dynamic behavior of the surface structures on the basis of a multilayer. To implement the BEM in calculating base proposed analytical method is effective for an arbitrary number of layers and the relations of their parameters. Given system approximating functions in the interface methods and proposed numerical integration formulas on the mating elements.

The paper is devoted to the generalized analysis of the research on the influence of the electric field and organic gelling additives on the properties of foam concrete. It is shown that the transmission of the electric field close to the resonance frequency oscillations of the particles in the binder or the introduction of slip mass gelling components lead to a significant increase in the physical and mechanical characteristics of the foam. 
Keywords: foam, impact properties, field modifiers.
