ABSTRACT
In this commentary, we try to make clearer the state of the art concerning the relation between mechanical contact interactions and the different notions of stresses. We emphasize the importance of the concept of virtual displacements. Its role has been recognized in Mechanics and in Continuum Mechanics long ago (see e.g., Vailati in Il principio dei lavori virtuali da Aristotele a Erone d'Alessandria, 113-128, ; Russo in The forgotten revolution, Springer, Berlin, , or Cosserat and Cosserat in Sur la Th�orie des Corps D�formables, Herman, Paris, ; Cosserat and Cosserat in Note sur la th�orie de l.action euclidienne, Gauthier-Villars, Paris, ), and it is central as well when starting with an expression of the power expended by internal stresses and deducing the form of contact interactions as when starting with some form of the contact interactions and developing a representation theorem for these contact interactions based on the Cauchy tetrahedron construction.
