I suggest you go through the book of Ever J. Barbero

https://www.amazon.com/Finite-Element-Analysis-Composite-Materials/dp/1466516895

The seventh chapter of the book is dedicated to the viscoelastic material you can grape some ideas from there

Keep us in touch about your work progress

Farzad Torabi

Thank you Bendie!

@Kitaranjan : why is the first and last Line a different syntax?
