Zusammenfassung:In lamellar liquid crystals, planar layers transform in special cases into curved layers taking the form of Dupin cyclides. In this paper we explain the transformation of the planar texture into the focal conic texture in terms of a buckling of the layers induced by the dilatation stress field existing around the dislocations.
