A Mathematical theory of moving disclinations is developed. Kinematics is derived for a continuous distribution of disclinations and disiocations as well sa for moving discrete disclination and dislocation lines. the concept of the plastic velocity is used to give the theory a symmetrical form. The new concepts of disclination and dislocation loop currents are introduced. The relation between the disclination theory and the incompatibility theory is given.
