How to find gR(t)=normalized shear modulus?

22 August 2020 1 438 Report

I want to use relaxation test data in abaqus. Abaqus wanted terms like gR(t)=normalized shear modulus at time (t) and long term normalized shear modulus to find prony series. can you help me in calculating (gR(t)) from relaxation test data OR any other way to find prony series from relaxation test data
