The elastic energy of a distorted flux-line lattice is calculated on the basis of a two-vortex interaction. Such a description is completely sufficient throughout the whole induction range between the upper and lower critical fields H/sub c//sub 1/ and H/sub c//sub 2/. Therefore it is possible to calculate all elastic moduli from a common potential consisting of two parts, one of a combined ''electromagnetic London type,'' the other based on the core overlap of the flux lines. The results are highly nonlocal and are in agreement with previous calculations of Brandt, but are modified near H/sub c//sub 1/ for small k (the ratio between the penetration depth and the coherence length).
