DISLOCATIONS, GRAIN BOUNDARIES AND FOCAL CONICS IN SMECTICS A

C. Williams , M. Kléman

Simple geometrical considerations predict 3 types of tilt grain boundaries in smectics A : curvature of the layers, arrays of dislocations and focal domains of equal eccentricity. These 3 possibilities are shown to exist in CBOOA (shear experiment). Their energies are discussed in terms of a simple model.
