Generate master curve for viscoelasticity

Hello,

I would like to generate a master curve (e.g. of the storage modulus) based on frequency-sweeps experiment for different temperatures.

Basically, I need to determine the shifts in order to construct the master curve. I want to automatize the process with Matlab, instead of shifting the data by hand. And I dont want to use WLF or Arrhenius methods.

I want to determine the shifts for each temperature s.t. I get a smooth master curve (minimize the error using least square).

Does someone have some good reference of a robust method? Or can anyone share a Matlab script?

Many thanks

Your approach sounds OK. I dont have a script to share 🙁
