摘要：
The purpose of paper is to analyze approximate behavior of harmonic wave propagating in a layered composite. The composite was made of materials with hyperelastic Blatz-Ko potential. Using two special cases of constitutive equation of Blatz-Ko material, it was assumed that the layers are filled alternately with foam rubber and homogenous rubber. The two extreme layers are infinite material areas separated by two layers on the lengths d1 and d2. According to the assumptions in the work it was discussed harmonic wave in the form of longitudinal and transverse acoustic wave. Numerical analysis was carried out based on the work [1] using the material constants obtained on the basis of experimental studies in works [2-4]. © 2020 Trans Tech Publications Ltd, Switzerland.
