Generate master curve for viscoelasticity
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?
Your approach sounds OK. I dont have a script to share 🙁
