2D Acoustic Velocities in Crystalline Materials
2D Acoustic Velocities in Crystalline Materials
The velocity of sound in anisotropic materials is directionally dependent. Three wave velocities may exist in any given direction: two transverse waves (primary oscillation perpendicular to the wave propagation direction) and one longitudinal wave (polarization in the same direction as the propagation). You can select the plane on which to view the velocity and whether to view the velocity surface or the inverse velocity (slowness).
