MS_VTI2
MS_VTI2 - generate elastic constants for a vertically transverse isotropic medium from xi, phi, eta parameters. Symmetry is in the 3-axis.
[C]=MS_VTI2(vp,vs,rh,xi,phi,eta)
Inputs: rh : Density (kg/m2) vp : km/s (isotropic average) vs : km/s (isotropic average) xi, phi, eta : Dimensionless anisotropy parameters
Output: C : Stiffness tensor (6x6 notation, GPa)
Calculates the elastic tensor for a hexagonal (aka VTI) medium from average Vp and Vs, and anisotropic parameters xi, phi and eta.
See, for example, Panning and Romanowicz (2006) for a definition of the parameters.
