This monograph presents a scientific research of asymptotic versions of continuum mechanics for composite constructions, that are both dilute (for instance, two-phase composite buildings with small inclusions) or densely packed (in this situation inclusions could be just about touching). it really is in keeping with the result of fresh study and encompasses a finished research of dipole and multipole fields linked to defects in solids. The textual content covers static difficulties of elasticity in dilute composites in addition to spectral difficulties. purposes of the mathematical versions integrated within the publication are in harm mechanics and in difficulties of layout of composite buildings that may be used as filters or polarisers of elastic waves.Dipole tensors are outlined in bankruptcy 1 either for scalar boundary worth difficulties for the Laplacian and for vector difficulties of elasticity. In bankruptcy 2 the dipole tensors are utilized in spectral difficulties related to domain names with small defects. bankruptcy three introduces a multipole procedure for static difficulties (both electrostatics and elasticity) in composite constructions containing doubly periodic arrays of round inclusions. bankruptcy four provides a multipole process for eigenvalue difficulties of electromagnetism and elasticity.

Fig. 4 Two circular inclusions at a close distance. It is noted that the length parameters are normalized in such a way that the distance between the centres of circular inclusions is equal to one. We consider a plane-strain deformation of the domain S by a load applied at infinity in such a way that the corresponding complex potentials are given by 4>aPPi.

The dispersion diagram constructed in accordance with the above formulae exhibits band gaps for the cases of bi-atomic structures of particles of different mass. It can also be shown that a correspondence can be established between this simple lattice structure and a continuum model describing fields in highly porous media.
