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
