For hexagonal anisotropy, how many of the 81 components of cijkl have zero values? For the values of ijkl listed in Figure 11.8, compute the Backus coefficients A, B, C, D, and E in equation (11.32)....

For hexagonal anisotropy, how many of the 81 components of cijkl have zero

values?

For the values of ijkl listed in Figure 11.8, compute the Backus coefficients A,

B, C, D, and E in equation (11.32). You will need to use the relationships for

hexagonal symmetry listed in equation (11.33). Make a plot of P velocity versus

azimuth.
