On considère une classe de matériaux poreux dont la phase solide est constituée de particules feuilletées. On étudie l'impact sur le comportement macroscopique de l'existence de forces d'interaction entre feuillets, dans l'hypothèse où les glissements feuillets sur feuillets sont libres. Les perspectives d'application concernent les argiles de la classe des smectites, pour lesquelles des forces de répulsion proviennent de l'interaction électrique entre les feuillets solides et le fluide interstitiel.
The solid phase of the porous material considered in this Note is made up of lamellar particles. The influence of interaction forces between platelets on the macroscopic behavior is addressed. The results provide a micromechanical basis to the modelling of the behavior of clays of the smectite group, for which repulsive forces arise from the electrical interaction between the solid platelets and the interstitial fluid.
