Dear Ali, here is a great book on tensorial properties including elasticity:
J.F. Nye, Physical Properties of Crystals, Clarendon Press, Oxford, 1998. It includes forms of elastic matrices for all possible crystal systems. -- Best regards, Max Popov Ph.D. student Materials center Leoben (MCL), Leoben, Austria. 2010/6/21 ali kazempour <kazempoor2000 at yahoo.com> > Dear All > 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 > > Ali Kazempour > > > > Fritz-Haber-Institut fax : ++49-30-8413 4701 > der Max-Planck-Gesellschaft > Faradayweg 4-6 e-mail: kazempou at fhi-berlin.mpg.de > D-14 195 Berlin-Dahlem / German > > _______________________________________________ > Pw_forum mailing list > Pw_forum at pwscf.org > http://www.democritos.it/mailman/listinfo/pw_forum > > -------------- next part -------------- An HTML attachment was scrubbed...
