WebBasic Introduction to Rheology - Technology Networks WebNov 1, 2011 · Flow curve. After a conditioning step of 2 min, the shear rate was increased from 0.1 s − 1 to 100 s − 1. The flow curve is then obtained by plotting the recorded shear stress (Pa) as a function of the applied shear rate (1/s). Viscosity and yield stress values were obtained by fitting the Casson equation to the data.
