Viscoelastic properties (curve fit) — Ansys Learning Forum

Viscoelastic properties (curve fit)

Hello,

I have a pressure ratio versus frequency graph from literature that I want to fit in the parameters of my viscoelastic material in my transient analysis. I will be using the Prony series. I know that to do curve fitting for Prony series I need the shear modulus versus time graph. I know how to get damping ratios from my data but I have no clue as to how to turn that into the shear modulus so I can do the curve fitting. Any help? Or should I change the way of thinking this whole thing?

Thanks
