Convert Stress Relaxation Data to a Master Curve and a Linear Viscoelastic Model

[@mortazaaghtar529]

what algorithm did you use to shift the curves and calculate the shift factors?

[@xchengzhang5409]

how can I find the video which talk about how to choose the time to reach relaxation strain?

[@kingkaruehat1086]

excuse me. i have creep compliance data .can i use it and change to Master curve .

[@valeryanpilov2602]

please specify where in the documentation for the program I can read about the search for WLF parameters (C1, C2, T0) ?

[@PolymerFEM]

We are moving very fast with with the code implementation of these types of models. The most recent version of MCalibration (> 7.1) make it easier to find the WLF params. The formal documentation is far behind... I guess that's why I'm doing some of these videos..

very helpful！Very detailed and clear explanation！it can solve us lots of problems of the connection between experiment and simulation. powerful tool，thank you !

Sir, can i ask you a question, right now im learning about rheology of bitumen. and im doing a modification bitumen with plastomer. right now im done with the DSR test, frequency sweep from 20 HZ to 100 HZ, in 20,30,40,50, and 70 deg Celcius. wht iam tryng to ask, is how you make the master curve, how to cinstruct it, any reference sir? if im tryng to do with WLF equation, do you have a video rference or something for me to learn. thanks you sir.

Thank you sir for your nice explanation. Is it possible to extract parameters if I have experimental stress relaxation data at different temperatures at different frequencies instead of different times ?

[@PolymerFEM]

Yes, that should be fine too.
