Betreff: [Wien] elastic-under-pressure-guide

Dear Wien2k users,
Can you guide me for finding equations of elastic constants under pressure?
For example for cubic compounds and for finding C44 under strain as:
 1      delta       0
 delta   1          0
 0         0       1/(1-delta^2)

the equation will be as:
E(V,delta) = E(V0,0)+V0(2C44*delat^2 + O(delta^4))


and now, i would like to know how i must correct this equation or other equations under pressure.
Please guide me

Sincerely,
Amir
