The physics of lamellarly structured fluids with small striation thickness scales can be successfully described by molecular theory arguments. Developments are based on the molecular theory of thin films (Rusanov and Kuni) and integral density function expansions. Results show that lamellarly structured fluids present local normal stresses as well as macroscopic pressure tensor values which are a function of striation thickness scales, molecular attractive parameters, and surface tension effects. This analysis should shed light on small scale effects during fluid mechanical mixing of fluids, rheology and stability of structured materials, as well as an organized summary of restrictions of macroscopic models on a structured continuum scale.
