The paper deals with nonlinear theory of defects like dislocations and disclinations either isolated or distributed with a certain density in an elastic medium with internal rotational degrees of freedom and couple stresses. The general theory is illustrated by finding the solution of problems of internal stresses induced in an elastic disc with an isolated wedge disclination as well as the distribution of such disclinations. Some results concerning the influence of the microstructure on the possibility of the hole formation along the dislocation line are presented.
