| 摘 要： | A plastic deformation zone near a screw dislocation is treated as an equivalent trans- formation inclusion by means of the Eshelby inclusion theory.A closed-form solution for deter- mining the interaction between a screw dislocation and a plastically deformed zone of an arbitrary shape is obtained by using the solution between a dislocation and an equivalent transformation inclusion.
