摘要：
The solution for the problems of straight disclinations with various directions of the Frank vector in an infinitely extended linear isotropic nonlocal elastic medium are derived assuming nonlocal moduli of two types. It is found that the stress fields have no singularities at the disclination lines but the logarithmical singularity at infinity remains as in the classical solution. Such a singularity is removed in a finite body, for example, in a case of circular cylinder with radius R.
