The equation of motions and the conditions on surfaces and edges betweenfluids and solids in presence of non-constant surface energies, as in the caseof surfactants attached to the fluid particles at the interfaces, are revisitedunder the principle of virtual work. We point out that adequate behaviors ofsurface concentrations may drastically modify the surface tension whichnaturally appears in the Laplace and the Young-Dupr\'e equations. Thus, theprinciple of virtual work points out a strong difference between the tworevisited concepts of surface energy and surface tension.

Interfaces endowed with non-constant surface energies revisited with the d'Alembert-Lagrange principle
