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
