摘要:
A “modified cone and plate” is presented as an alternative geometry for the measurement of material functions in a rotational rheometer. It gives a significant improvement in the quality of the signal for the normal force and makes it possible to reach higher shear rates prior to the point at which the sample fails. A theoretical and experimental study of this new geometry which can be used for normal force and torque measurements has been developed to obtain the first normal stress coefficient and viscosity information.
