Influence of non-homogeneous uniaxial pressure on the propagation of bulk acoustic waves in crystals

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/sub 12/GeO/sub 20/ (23 point symmetry) have been made.
