The paper investigates the dynamic problem of the linear theory of viscoelasticity for a layered rod of a periodic structure. The problem is solved by the approximate analytical averaging method. In the long-wave approximation, an analytical solution of the problem of the propagation of harmonic waves in a composite rod based on the Maxwell model is obtained.
