Paper Abstract

Elastic wave velocities as a function of applied stress are analysed in multilayered and 1-D phononic structures. The analysis is conducted by the means of the acoustoelasticity theory for isotropic elastic structures with application of this theory to stable formulation of stiffness and hybrid matrix methods for the eigenvalue analysis in the stressed elastic structures. The reformulated matrix methods are used for obtaining modal solutions, reflection and transmission coefficients for different multilayered media cases. Floquet wave analysis is presented for the stressed 1-D phononic structures. The analysis is supported by numerical examples.
