Lois de comportement d'interface

Abstract : The notion of interface is extended here to domains which present strong normal gradients along a thickness larger than the molecular scale, but small enough in comparison with a macroscopic scale, significant to the interface surrounding. Some balance equations, describing the evolution of the surface proprieties are established. To directly solve the system with the surface variables, it is necessary to find some complementary constitutive equations, closing this one. Two ways are proposed: the first one is a transposition of some equations of state and relations, applied usually to volume variables, to surface ones. The second one is a direct research of some constitutive relations by a dimension analysis.
