In the context of wave propagation in damaged (elastic) solids, an analytical approach for normal penetration of a plane wave through a doubly periodic array of cracks is developed. Using a uniform approximation in a one-mode range previously obtained, we give explicit representations for the wave field throughout the structure (including reflection and transmission coefficients) and for the relevant dispersion equation.

Abstract
In the context of wave propagation in damaged (elastic) solids, an analytical approach for normal penetration of a plane wave through a doubly periodic array of cracks is developed. Using a uniform approximation in a one-mode range previously obtained, we give explicit representations for the wave field throughout the structure (including reflection and transmission coefficients) and for the relevant dispersion equation.File in questo prodotto:
