The procedure from Section 5.5.2 can now be implemented to determine the uniaxial |E*|dynamic modulus mastercurve, using the fitted GPL parameters as inputs. For the prescribed time range of the shear relaxation modulus data of Figure 12, 0.1 < t < 100 seconds, this would correspond to a frequency range of 0.0008<t<0.8 Hz based on Equation
