[Pw_forum] elastic constants

[GAO Zhe]

In my opinion, the methods, to find elastic constants for both of CsCl-structure and NaCl-structure, should be same principlely, because of the cubic lattice.

can any one suggest me how to find the elastic constants in CsCl phase
because i know by distortion stress strain  relation i can find the elastic constants in B 1 phase (nacl)
by orthorombhic and tetragonal distortion 
what is the difference between two phase determining the elastic constants
