ABSTRACT:
Method of determining at least one dynamic characteristic of a sample of a deformable solid or fluid material, comprising: the contacting of said sample (24, 42) with at least one interaction surface (23, 25, 41a, 41b); the application of a relative movement between said sample (24, 42) and said interaction surface (23, 25, 41a, 41b); and the measurement (26) of at least one dynamic or kinematic quantity in respect of the sample (24, 42) and/or said interaction surface (23, 25, 41a, 41b), wherein said interaction surface (23, 25, 41a, 41b) has an intrinsic wettability with respect to the material that is higher than that of metals.Device for implementing this method.According to particular embodiments, said interaction surface (23, 25) is made of high-density sintered ceramic or made of single crystal silicon or germanium, preferably having a zero open porosity and an arithmetic mean roughness parameter of less than 12.5 μm and preferably between 0.4 and 1.6 μm.
