Scattering of High Frequency Sound Waves in Polycrystalline Materials. II

Abstract

The calculations of a previous paper, which were based on a simplification in that the effective elastic properties of each grain were described by just Lamé's two elastic constants, are generalized to take into account the fact that an elastically anisotropic medium has actually several independent elastic constants. The final expressions for the attenuation coefficient of shear and dilatational waves exhibit qualitatively similar features as the corresponding expressions of the previous paper but differ quantitatively from them.
