Webthixotropy, shear-banding, and of slip of the material on the surface of the tool used for rheological measurements [6,7]. As a result, sensitivity to loading conditions, ensuring kinematic homogeneity, and unambiguous control of history of deformation each pose particular challenges for rheological measurements of yield stress fluids [5,8]. WebRheological parameters are calculated from the measured values torque, deflection angle and speed using conversion factors (see Table 1). All further parameters, such as viscosity, are not measured but calculated. Table 1. Measuring values and rheological parameters with the conversion factors. Rheometer Design
