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

摘要

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