A spatially-periodic structure consisting of a large number of homogeneous isotropic elastic layers with different thicknesses, densities, and elastic material properties are considered. Further, the layers should be perfectly bonded at the material interfaces. It is assumed, that an initial static displacement produces waves propagating across this structure. The aim of this paper is to calculate the subsequent positions of the wave fronts corresponding to different propagation modes. [References: 11]
