| An efficient analytical approach for developing the technique for comparison of anisotropic acoustical crystals of a hexagonal, cubic and orthorhombic structure by their elastic properties was offered in the three-dimensional statement. The mentioned approach is based on the reducing of a complete system of motion equations for spatial waveguide objects of such materials to solution of independent generalized wave equations by substituting the dependent components of displacement vector with the independent components of vector wave potential. The developed technique is based on distinguishing the common part and representative terms in the fundamental solving equation and on obtaining the generalized elastic characteristics. For a wide range of real anisotropic acoustical crystals, the behavior of the generalized elastic characteristics has been studied and the corresponding criteria of comparison of such materials have been developed. |
