Eshelby configurational force

WebJul 1, 2024 · Abstract. In this paper, an innovative interface fracture criterion is proposed based on the concept of configurational forces in material space. In this criterion, the crack-tip configurational forces as the driving force are introduced to describe the interface crack evolution under mixed-mode loading conditions. And it assumes that the interface … WebAug 14, 2007 · The Eshelby stress (static energy momentum) tensor is derived for bone modelled as an inhomogeneous piezoelectric and piezomagnetic Cosserat (micropolar) medium. The divergence of this tensor is the configurational force felt by material gradients and defects in the medium.
