Coefficients of reflection and transmission of transverse and longitudinal acoustic wave in the Blatz-Ko material

Abstract

The purpose of this paper is to analyze the propagation of transverse and longitudinal acoustic wave in a composite made of hyperelastic Blatz-Ko material. Composite consists of a homogeneous layer of predetermined thickness d separating two infinite homogeneous material areas. In the paper it is assumed that the middle layer is filled with a homogeneous rubber (ƒ=1), whereas the external areas with foam rubber (ƒ=0). The final effect of paper are graphs of coefficients reflection of transverse and longitudinal acoustic wave, propagating in this composite
