Abstract

The development of the theory of propagation of small amplitude bulk acoustic waves in crystals under uniaxial mechanical pressure has been made by taking into account the condition of non-homogeneous deformation of crystal sample. It has been shown that the path of bulk acoustic waves will be a function of the non-homogeneous deformation. As an example, calculations for some crystal directions of cubic crystal Bi ₁₂GeO₂₀ (23 point symmetry) have been made
