Good Day All,
I am trying to employ the WLF for an ageing forecast.
We have performed accelrated ageing at 50, 60 and 70 C for 4 months and then measured various properties, one of particular relevance being the elongation at break.
I thimk I understood the principles of the WLF approach, but I am struggling in its application.
Especially how the coefficients should be detrmined is mysterious to me. I am generally conversant with numeric techniques, but I am unclear on what the best fit should be based upon.
I attach the raw data, should anyone be interested.
any help would be the most appreciated.
Thank you very much
