Transverse and Longitudinal Harmonic Wave in Layered Structure Made of Hyperelastic Materials

Abstract:

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].
