Principles of Measuring Viscoelastic Properties
Innovations for the full measurement of the viscoelastic properties of fluids

Knowledge of the dynamic characteristics of materials is essential for their application and use under optimal conditions. Of the three states of matter, the liquid state—which is difficult to model and whose behavior is hard to predict—is certainly the least well understood. The systematic study of the dynamic properties of fluids is a relatively new discipline. With the emergence of commercial rheometers, rheology has rapidly established itself as the discipline for characterizing fluid or deformable materials at the macroscopic scale. Its principle essentially consists of examining the response transmitted by the material when subjected to dynamic mechanical stress.

This technique is entirely dependent on the conditions of interaction between the material and the substrate that transmits the stress. However, very few studies have focused on analyzing the influence of the choice of surface...
