Validation of the linear viscoelastic region of a Silicone Polymer and a Worm-likeMicellar solution using normal force to determine the onset of non-linearity
关键字:Normal force, Linear viscoelastic region, Oscillation, Non-linearity It is well known that shear oscillation of a non-Newtonian sample creates normal stresses. These stresses can therefore be used to verify whether any particular oscillatory measurement has been made within the sample’s linear vis...
