Аннотация:The work is devoted to the analysis of the spectral properties of a boundary value problem describing one-dimensional vibrations along the axis O x1 of periodically alternating M elastic and M viscoelastic layers parallel to the plane Ox2x3. It is shown that the spectrum of the boundary value problem is the union of roots of M equations. The asymptotic behavior of the spectrum of the problem as M → ∞ is analyzed; in particular, it is proved that not all sequences of eigenvalues of the original (prelimit) problem converge to eigenvalues of the corresponding homogenized (limit) problem.
