The solution is given for the problem of screw dislocation in nonlocal elasticity. The shear stress and the elastic energy are calculated. Interestingly enough none of the classical singularities for the stress and energy exist in the nonlocal solutions. Estimates are provided for the critical shear stress which will produce a single dislocation of one atomic distance. Author
