Has anyone suitable reference about elastic constant matrix for Hexagonal lattice .
In principle does this elastic constants differ in each Hexagonal shape crystals?( I mean for example between NiAs-type material that has Hexagonal lattice and HCP lattice ) .
Another question: is any reffernce about how to connect the elestic constant of Hexagonal to phonon frequency?
Thanks a lot
