Abstract
A molecular approach is utilized to evaluate the Frank elastic constan ts for discotic nematic liquid crystals, by utilizing the Maier-Saupe approximation. By choosing a suitable geometry for the interaction vol ume, the results are analysed in a lyotropic nematic context. It is sh own that the elastic constants depend on the micellar-shape anisotropy defined as the ratio between the micellar diameter and the bilayer th ickness.
