Chimenti. The propagation of waves through nonhomogeneous elastic material, with a periodic structure of elastic constants and density variation, can be conveniently treated in terms of Floquet waves. These are quasi-periodic waves, propagating in one direction, the displacement profiles of which change with time, but repeat after the wave has traversed a complete cell of the tula-music.com by: This paper is concerned with the analysis of elastic Elastic waves in composite media and structures book generated by localized dynamic sources in structural composites.

The damage can be external, involving low-velocity foreign object impact. Mar 01,  · Abstract: Propagation of elastic waves in periodic composite structures has recently attracted great attention.

These periodic structures can stop wave propagation in certain frequency ranges (i.e., band gaps) and have potential applications in frequency filters, wave guides, vibration isolators, and energy harvesting devices.
