Very helpful Dr. Bergstrom. But how can one estimate the lower limit for stress in stress relaxation in the absence of experimental data. Can storage modulus master curve from DMA be used to estimate the lower bound for stress?

Yes, in theory that should work. But make sure linear viscelasticity is valid at all temps and strains of interest.

Very Interesting, I like your presentation style and content very much. Is it also possible to convert/predict long term relaxation data from creep data at a range of stresses, such as the creep data from the datasheet in your PC creep video: kzitem.info/news/bejne/o5CatIaLraCAfn4 . Hope the question makes sense :) /Joakim
