| Abstract: | The self-consistent dynamics of a dislocation ensemble in an elastic field of a planar mesodefect has been considered within
the kinetic approach. The effective Airy stress function for a planar mesodefect, which takes into account the screening effect
of a system of distributed dislocation charges, has been obtained. Coordinate dependences of the stress tensor components
and the dislocation charge density for the considered screened system have been found. Its elastic energy and misorientation
of the regions adjacent to the planar mesodefect have been calculated. |
