Basic concepts of interface and interfacial layer are first introduced. Orthogonal curvilinear coordinate analysis, used to study interfacial zones depending of time, is presented. Classical 3D and 2D thermodynamical relations are reminded and second gradient formulation is introduced. General balance laws are written inside the interfacial layer and then, by using an asymptotic approach, balance laws are obtained for interfaces. The constitutive relations are deduced from thermodynamics of irreversible processes. More or less classical examples are given to illustrate the purpose.
