Eshelby configurational force
WebAbstract: "The standard forces associated with continua arise as a response to the motion of material points. That additional configurational forces may be needed to describe internal structure is clear from Eshelby's work on lattice defects. Eshelby's studies are statical, based on variational arguments. I take a different point of view. I believe that … WebSep 10, 2013 · Furthermore, a configurational or Eshelby-like force at the insertion point, not present in the classical problem, needs to be accounted as recently discovered [40] …

WebJun 11, 2016 · The concept of material configurational stress (or called Eshelby stress) is used to describe the material yielding state and to predict the crack propagation in this paper. The equivalent configurational stress $$(b_{v})$$ ( b v ) is introduced to successfully describe the elastic–plastic boundary near the crack tip. Moreover, the crack … WebThe formulation is developed in the framework of configurational mechanics and solved numerically using the finite-element method.
