Dislocation Symmetries in the Integral Theory

The symmetry of the displacement field is investigated for the case that a dislocation runs normal to an axis of twofold symmetry. The three components of the displacement field are found to be even and odd functions of the three components of the Burgers vector. Calculations are done in the “integral theory”. The forms of the basic matrices Q, B, and S for the symmetry considered are found as well.
