The concept of configurational force has been introduced by Eshelby to describe the motion of massless (for instance voids, microcracks, vacancies, or dislocations) or heavy (for instance inclusions) defects within a solid body as the result of mechanical or thermal loading. This concept has been exploited through the years for modelling the crack-driving force in fracture mechanics, the Peach–Koehler force of dislocations, or the material force developing on a phase boundary in a solid under loading. The action of configurational forces on elastic structures has been theoretically and experimentally proven in the presence of a specific movable constraint: a frictionless, perfectly smooth and bilateral sliding sleeve.
