I am currently writing my Masterthesis and I need help in modelling a viscoelastic material in ANSYS Mechanical. I don't know how exactly I should add my material properties in the Engineering Data field.
I experimentally measured the shear modulus G(t), and calculated the Bulk Modulus K(t) with the following formula: K(t) = 1/(3*(1-2nu)) * E(t), with E(t) = stress(t)/strain. - Attached, you can find an example with my data for G(t)-.
When I run my model with only this two Viscoelastic Test Data series, I get this error:
Elasticity is required, but is currently undefined.
I tried to add the required Isotropic Elasticity Property Data (Youngs Modulus and Poisson's Ratio) but when I run my model again, I get the same results as if I had only a Linear Elastic Material, it returns the same value. Ansys is not considering my viscoelastic property data I gave him.
Thank you and I hope You can help me!
