Therefore the complete form of the functional (1) is suggested for elastic-plastic materials.
For the perfectly plastic materials the is determined by the following relationship [5]; (12) where is a proper yield criterion suited for this problem and is the elastic coefficient of the hook’s law.

Introduction A Dislocation and dipole are the common line defect in crystal materials.
The interaction of other defects in materials, such as cracks, holes, rigid lines, and so on, with dislocations and inhomogeneities is important for researching the strengthening and toughening mechanism and damage effect of materials.
The two materials are assumed to be perfectly bonded along the interface.

Introduction Amorphous and nanocrystalline metallic alloys present a new category of materials with interesting mechanical, electric and magnetic characteristics [1-3].
However the applications of metallic glasses and nanocrystalline materials are still restricted due to high purity and a high price of the precursors.
