Dynamic Interaction of Elastic Composites and an Acoustics Fluid

Abstract

Work has been completed on the following topics: (1) One-dimensional response of periodically layered composites in contact with an acoustic fluid; (2) Applicability of Floquet theory to bounded periodic domains; (3) Two- dimensional waves in anisotropic layered composites; (4) The surface impedance tensor -- Rayleigh waves in anisotropic layered composites; (5) Rayleigh-Lamb waves in anisotropic layered composites; (6) Scholte-Gogoladze-like waves at the interface between a fluid and an anisotropic layered composite; and (7) An algorithm for the computation of the surface impedance tensor of anisotropic layered media. Keywords: Plane strain waves; Wave propagation; Matrices mathematics; Laminates/interactions.
