Oscillatory tests
Complex viscosity, moduli G' and G''
under oscillation
During Oscillatory tests the measuring geometry oscillates around the rotation axis instead of moving constantly in one direction. Therefore the measured values show not only the viscous behaviour but also the stiffness (elasticity) of the sample.
Amplitude sweep

Determination of the linear-viscoelastic (LVE- ) area

Frequency sweep

Determination of the Storage modulus G' and the loss modulus G''
