| Abstract |
The three-dimensional dynamic problem of forced oscillations of an orthotropic two-layered plate in the presence of internal friction in the layers is solved by the asymptotic method. It is
assumed that the friction is proportional to the velocity of the points. The values of stress set on the
front faces of the double-layered packet harmonically vary in time. The general asymptotic solution of
the interior problem is found. It is shown that, due to friction (dissipation), the oscillation amplitudes
always remain finite, while, in the absence of internal friction, there are frequencies at which the oscillation amplitude becomes infinite. |
