Transient waves propagating parallel to the layers in a linear elastic or viscoelastic layered composite are studied. A step load in time is applied at the boundary x = 0 and the head-of-the-pulse asymptotic solution is obtained for large x and large time t. For viscoelastic composites the interaction between the dissipation and the dispersion is controlled by a parameter γ that contains the material mismatch of the layers and the distance: propagated by the waves. As the distance increases, so does γ, and the oscillatory response diminishes. For elastic composites, we show how the oscillatory response depends on the mismatch of the material properties and the thicknesses of the layers. We show that there are composites other than the one with zero mismatch for which the oscillatory response is almost nonexistent. |
