Hi,
I am trying to evaluate viscoelastic properties of a rubber material using Dynamic Mechanical Analyser. The frequency range of my interest is up to 8 KHz. I read in literature that using Time Temperature Superposition technique (or frequency shifting) we can convert data at extended temperatures to higher / lower frequencies.
Can someone suggest if there is a formula or thumb rule as to the minimum temperature down to which I should test the sample for getting master curve up to 8 KHz ?
Thank you.
Kind regards
Kiran
