Abstract

The heterogeneous structure is considered as three-dimensional periodic structure in which the cell in the form of a rectangular parallelepiped (the independent block) with viscous and compressed non-uniform filling is allocated. For the independent block from the decision of regional problems for the equations of Nave – Stoksa the descriptor in the form of an impedance matrix is defined. From conditions of the theorem the Flock for an impedance matrix the characteristic equation of definition of complex constants of distribution of waves in periodic structure is received.

Key words

independent blocks, heterogeneous structures, periodic structures, the theorem the Flock, an impedance matrix.
