P-wave ray velocities and the inverse acoustic problem for anisotropic media
Original language description
The specific features of the calculation of ray velocities of quasi-longitudinal waves in anisotropic media have been considered. A technique for calculating elastic constants using P-wave ray velocities measured in an ultrasonic experiment on spherical samples is presented. It is shown by an example of tabular data that elastic constants С11, С22, and С33 and combinations of constants (С12 + 2С 66), (С13 + 2С55), (С23 + 2С44), (С14 + 2С56), (С25 + 2С46), and (С36 + 2С 45) can be calculated most accurately for the general case of anisotropic media with elastic properties of arbitrary symmetry. Since the determining system of equations is illconditioned, the values of elastic constants entering these combinations depend on the choosed initial approximation.
