Définition d'énergies d'interfaces à partir de modèles atomiques

We present here a possible derivation of interfacial energies from simple atomistic models, such as pair potential energies. In order to do so, we first extend the result of Blanc et al. [Arch. Rational Mech. Anal. 164 (4) (2002) 341-381], and then apply it to study in the case of an interface the limit of the energy as the atomic spacing goes to zero. To cite this article: X. Blanc, C. Le Bris, C. R. Acad. Sci. Paris, Ser. I 340 (2005).
