I have a bunch of test data for a viscoelastic material and I would like to distill this down to a viscoelastic model in Abaqus without using a custom material subroutine. And quite frankly I am not sure where to start.
Data I have:
TCE vs Temp
Viscosity vs Temp
Cp vs Temp
For now I can ignore bulk modulus but I was wondering if someone could give me some guidance in taking the test data and putting this into a shear relaxation modulus. A fit has already been done to get this into a TNM model so I have the TCE (liquid and and solid), time constant, activation energy, and the parameters of a TNM model.
Is it possible to use this information in a way that would not require a series of custom material/property routines? Or is that really the only way?
Any help is appreciated.
