Polymer viscoelasticity and the relaxation modulus 

you've proven that not everyone can deliver this kind of information as logical and clear as you just did. you have my gratitude sir

I’m a PhD student, and you just saved my life.

awesome explanation fullfilling my PhD course lol

awesome thank you!!

This is explained perfectly. Getting ready for my PhD comprehensive exam and this just saved me a ton of time. Thank you.

Thank you veeeeeeeeery much

nice, clear video.

hi . this course was very helpful for me. great job and tnx a lot

very informative intro for a rookie, thx.

Thank you very much again!

hi

Thanks for the video 👌

In Abaqus software, the viscoelastic model of material can be defined based on the shear test data of normalized shear compliance j(s) or modulus g(R). Please guide me on the way to calculate j(s) or g(R) from the stress relaxation data.

They should call it quartzy instead of glassy shouldn't they!

Sir and Dear Friends I have a question. How can we fixed the length ? When we apply force should not we observe elongation ? I think from Stress= Module x Strain. If strain is fixed and stress is decreasing it means modulus of material also changes ? Thank you.
