ABSTRACT
In this work, a general approximate solution for the configurational force between edge
dislocation and inhomogeneity of an arbitrary shape and properties with coupled thermo-
mechanical loads was developed on the basis of the Eshelby equivalent inclusion theory.
The effect of temperature-dependent elastic properties, thermal expansion coefficient and
yield strength on the configurational forces was analyzed. Furthermore, the configurational
force considered to be the driving force for dislocation migration was innovatively used to
investigate the interaction mechanism between graphene and internal defects of a metal.
