4. 3 Evaluation of Oscillation Measurements Oscillation modes are a quite complex method for studying materials rheological parameters In opposite to the evaluation of measuring standard flowcurves here the vessel is sinusoidal oscillating at different frequencies and amplitudes The resulting force on the probe is also a harmonic function if the ma terial has a linear and time independent behaviour There are two stan dard tests used here e With an amplitude sweep the vessel is oscillating at a constant frequency for example 0 5Hz The amplitude is increasing or de creasing e With the frequency sweep the deformation amplitude is kept con stant for example 1 degree but the frequency may increase or de crease during the test for example from OHz to 3 Hz The test procedure is defined within the profile see chapter 21 Oscillation 3 000 Angle grd ioo Semen E ee LESEN ee aaa ee 0 00 10 00 20 00 30 00 Time s Figure 31 Vessel angle over time and resulting force on the paste probe Material wallpaper paste Instrument Viskomat XL We will now focus on the frequency sweep In the picture 31 you may see the angle of the vessel over time black function and the measure torque red curve You see that the delay between stress and strain is varying over time also the amplitude of the strain is changing over frequency In figure 32 you see the angle and the stress r plotted on the ordinate and a
